This allows a {tab} in a string bind to indent a marked region.
This fixes https://savannah.gnu.org/bugs/?65859.
Problem existed since version 7.0, since braced function names
were introduced.
Activating --modernbindings when the binary's name starts with "e"
interferes with Debian's alternatives system that symlinks `editor`
to `nano` in a default install.
(Also: why "e"? It would have made more sense to check for "m",
similar to the checking for "r" for a restricted nano.)
This reverts commit 580eaf29 from fifteen months ago.

The names of the authors were retrieved from:
git log -p --follow syntax/<name>.nanorc
and from:
git log -p --follow --all -- doc/nanorc.sample
For some files the original author is unclear, or
the file is/was too small to mention an author for.
The typo prevented several keywords from getting colorized.
This addresses https://savannah.gnu.org/patch/?10459.
Bug existed since version 2.1.6, commit 513157df,
since the Fortran syntax was introduced.
The succinct function descriptions in the help lines are not shown in
reverse video by default, so they are not bolded by -D/--bold either.
Also, mention 'promptcolor' and 'minicolor' where they were missing.
Prevent also the toggling of Append and Prepend. All four functions
should not be available in restricted mode, and are absent from the
WriteOut menu in that mode, but using {browser}, {backup}, {append}
or {prepend} in a string bind allowed to bypass the menu checks.
This fixes https://savannah.gnu.org/bugs/?65819.
Problem existed since version 7.0, since braced function names
were introduced.
Since version 3.2, commit 5ca444e5, nano reads the nanorc files also
in restricted mode (when not also --ignorercfiles is given), meaning
that syntaxes are available and that a specific syntax can be selected
on the command line. So, the --help output in restricted mode should
list the relevant option: -Y<name> / --syntax=<name>.
(This should have been part of commit b81995af from six years ago.)
The bindable function 'nowrap' has been deprecated for three years,
since version 5.5, commit e14127b8.
(The obsolete options --nowrap and 'set nowrap' continue to exist.)
When one has installed additional syntaxes, one tends to forget
what exactly is there. So it's nice to be able to list them.
The syntaxes are listed in the reverse order in which they were
read: the most recent first.
The long form of the option is, of course, --listsyntaxes,
which can be abbreviated to --list.
This fulfills https://savannah.gnu.org/bugs/?65779.
The feature was suggested by `davidhcefx`.
Stop doing colon parsing by default, to avoid surprises and frustration
for users that have filenames that end in a colon plus digits.
The equivalent rcfile option is, of course, 'set colonparsing'.
Using +1, or similar, before the filename disables any colon parsing
and the filename is taken as is.
Starting from the end of the provided filename avoids needlessly looking
at colons that are somewhere in the middle of the path or the filename.
It also avoids inconsistenly interpreting a specified line number as a
column number when the filename itself ends with a colon plus digits
and the filename without the colon plus digits exists too.
This also removes the eliding of a backslash before a colon, which
would mangle the filename if the name actually contained a backslash
followed by a colon.
Negative line and column numbers are no longer allowed when using the
colon notation.
This fixes https://savannah.gnu.org/bugs/?65781,
and fixes https://savannah.gnu.org/bugs/?65782.
Problems existed since version 8.0, since colon parsing was introduced.
While updating the screen, ncurses by default polls the input source
now and then to see if there is new input, and if so, stops updating
the screen and waits for the next call of doupdate() or refresh().
https://lists.gnu.org/archive/html/bug-ncurses/2024-05/msg00077.html
Disable this polling, as it is just a waste of time, and there *might*
be situations where the intruding keystroke does not actually trigger
a new update, which could result in a half-updated screen.
When the file 'foo:24' exists (but not 'foo') and the user wants to
use the colon notation to place the cursor on a certain line, then
nano would first interpret the given line number as a column number,
before noticing that 'foo' does not exist and then skipping the first
colon. So, when such a misinterpretation occurs, the column number
needs to be reset to zero.
When the user specifies, on the command line, a filename that ends with
a colon plus digits, and that filename exists in the file system, then
open that file, instead of interpreting the digits as a line number.
Also, if the filename stripped of the colon plus digits does not exist,
then do not interpret the digits as a line number either but treat them
as part of the file name.
Before this change, the user would have to escape the colon whenever
they wanted to open a file whose name ended with a colon plus digits.
Now the user needs to escape the colon only when 'foo' exists and they
want to create, say, 'foo:24'.

Nano does not recognize the urxvt escape sequences for other
<Alt+cursorkey> combinations either. And with the previous
two commits, the urxvt user can now "help themselves".
This reverts commit 363a4378 from three days ago.
This makes those keystrokes work too when --raw is used.
But more importantly: these raw sequences can be used in an
~/.Xresources file to override the odd behavior of urxvt for
those keystrokes, making the previous commit redundant.
When pressing Alt+Home/Alt+End on urxvt, urxvt either sets the high bit
of the last byte in the sequence for Home/End (when Meta8 is True), or
sends an extra escape before that same sequence (when Meta8 is False).
Accommodate for this bug by recognizing the produced code sequences.

The 'openfile->fmt' element gets initialized to 'UNSPECIFIED',
so the code has to take that possibility into account.
This fixes https://savannah.gnu.org/bugs/?65676.
Bug existed since version 8.0, commit fe4f74f6.
This closes a window of opportunity where the emergency file could be
replaced by a malicious symlink.
The issue was reported by `MartinJM` and `InvisibleMeerkat`.
Problem existed since version 2.2.0, commit 123110c5, when chmodding
and chowning of the emergency .save file was added.
When recording a macro over a laggy connection or on a slow, overloaded
computer, several keystrokes could be recorded in one burst, and if any
but the last of those keystrokes was the shortcut for `runmacro`, then
running the macro would lead to an infinite loop and nano would hang.
This new implementation of snipping the "last keystroke" will, however,
snip *too many* keystrokes when several of them were recorded at once
and `runmacro` or `recordmacro` was among them, resulting in a cropped
and thus misrecorded macro. But... that's better than hanging.
In general, though, the user should be slow and deliberate when
recording a macro: waiting for nano to have processed the last
keystroke before typing the next.
This fixes https://savannah.gnu.org/bugs/?65649.
The issue was reported by `correctmost`.
Problem existed since version 2.9.0, since macros were introduced.
These calls of do_delete() were meant to delete just one character,
but over time do_delete() morphed into doing also other things...
Change the calls to invoke the correct function instead.
(This also avoids snipping any zero-width characters that come after
a snipped space, as that is probably not what the user wants.)
This fixes https://savannah.gnu.org/bugs/?65636.

Bug existed since version 3.2, commit ae3ec178,
when --zap was introduced.
Redoing an automatic hard-wrap while one or more chunks of the affected
line are offscreen, can leave 'firstcolumn' with a value that doesn't
fit the situation. So, make sure that it has a valid value.
This complements the previous commit.

Bug existed since version 2.8.6, commit e375995d.
When one or more chunks of the current line are above the viewport,
and this line gets hard-wrapped, then 'edittop' needs to be advanced,
otherwise the first row could be blank -- representing a chunk that
doesn't exist any more.

Bug existed since version 2.8.6, commit e375995d.
When opening a nonexistent file with nano, it likely consists of only a
name without any path component, and thus without any slash. So when a
file regex checks for a slash, it should check also for start-of-string.
This fixes https://savannah.gnu.org/bugs/?65591.
Problem existed for the Makefile since version 2.9.8, commit 22663f8a,
and for .profile since version 3.0, commit 4a268678 (but earlier, nano
did not recognize .profile files at all).
When an entirely blank line is trimmed (when --autoindent is active and
Enter is pressed while the cursor is at the end of the current indent),
the mark needs be adjusted *before* 'current_x' is zeroed, otherwise the
mark gets moved too much to the right, which causes the region to become
bigger than what the user intended, or leads to accessing unallocated
memory.
This fixes https://savannah.gnu.org/bugs/?65586.

Bug existed since version 2.8.1, commit 005ee8ed.
