77a8841d25 tweaks: elide unhelpful occurrences of the word "will"
In most cases, "will" is just a filler word and doesn't improve clarity.

And in the bargain improve two descriptions.

7d8f13b9f7 build: use the standard autoreconf invocation
As version 0.20 of `autopoint` no longer overwrites 'extern-inline.m4',
there is no need any more for the custom calls of the various parts of
`autoreconf`.

This effectively reverts commit 4a1db96d from two and a half years ago.

ec177c84b3 build: require version 0.20 of gettext for building nano from git
Gettext-0.20 is the first version where its `autopoint` does not
overwrite the newer 'extern-inline.m4' from gnulib.

Version 0.20 is five years old, so most users will be on a distro
that includes that version of gettext or a newer one.

Also, reshuffle Alt+T for balance, slightly reword the description
of Alt+A (as it differs in nature from the other toggles), and add
some spaces for better alignment.

dff779e3ad tweaks: in FAQ, use 'id' attribute instead of empty anchor with 'name'
The 'name' attribute for the <a> tag is deprecated -- 'id' is the
standard attribute that can be used in almost every tag.

ef1c9b9f2b tweaks: implement do_center() with a single call instead of three
This works because the main loop sets 'cycling_aim' to zero

498154804c bindings: let ^L put the cursor line at center, then top, then bottom
Something similar can be achieved with:

  bind ^T "{center}{bottomrow}{center}{toprow}" main
  bind ^B "{center}{toprow}{center}{bottomrow}" main

But that requires allocating two extra shortcuts, and it works right only
when the edit window has an odd number of rows, not with an even number.
Also, this new ^L behavior is available by default, out-of-the-box.

d1c723bc14 new feature: add bindable function cycle that pushes cursor line around
On the first call, `cycle` centers the line with the cursor, on the
second consecutive call it pushes that line to the top of the viewport,
and on the third consecutive call to the bottom of the viewport.

d477bfd4ee tweaks: drop two redundant conditions
The function do_tab() is only ever called when in the main edit window,
and never called while a bracketed paste is in progress.

(The two conditions were thoughtlessly copied when this fragment of code
was moved here three commits ago.)

6c81f60914 moving: use edit_scroll() only when scrolling one row is enough
When softwrapping with a tabsize larger than the width of the viewport,
scrolling one row when the cursor goes offscreen might not be enough,
so in that case use edit_redraw() instead.

This fixes https://savannah.gnu.org/bugs/?65860.

a98f82e27b startup: no not activate --modernbindings when name starts with "e"
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.

c70e6919c2 syntaxes: mention the original author of most of the syntax files
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.

Prevent also the toggling of Append and Prepend.  All four functions

or {prepend} in a string bind allowed to bypass the menu checks.

ea07eb6aa3 help: show option -Y/--syntax in --help output also in restricted mode
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>.

49c2f5dea9 new feature: option -z lists the names of available syntaxes
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`.

02dd0b4ed5 options: require --colonparsing/-@ to parse colon+number after a filename
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.

add945e717 files: look for digits and colons starting from the end of the filename
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.

259a3c70e3 general: disable the type-ahead checking that ncurses normally does
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.

2445e77535 files: avoid mistakenly setting the column number to a given line number
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.

54c8cb8c81 files: when a filename with a colon and digits exists, open that file
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'.

363a4378b7 input: provide for urxvt setting a high bit or sending an extra escape
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.
