The few calls of the injection routines that had 'filtering' set to
TRUE have already filtered out ASCII control codes earlier on. And
in the case of injecting a completion, this completion only contains
word-forming characters -- and if the user somehow added a control
code to the word-forming characters, then nano should NOT filter it
out, so in fact that setting of 'filtering' to TRUE was mistaken.
Note that this filtering did not filter out 0x7F (DEL). But that is
fine: it should not occur in the input stream at that point anyway,
as it gets translated to either KEY_DC or KEY_BACKSPACE earlier in
the keyboard parsing routines.
When opening multiple files, and the first of them has a lock file,
and the user chooses to not open the corresponding file, then nano
should NOT create an empty buffer in its stead.
This fixes https://savannah.gnu.org/bugs/?57777.
Bug existed since lock files were introduced, in version 2.4.0,
specifically since commit 6948d2e7.
When copy-pasting has resulted in a nanorc file with DOS line endings
(CR+LF), then silently ignore the carriage return, to avoid printing
an error message that partly overwrites itself.
This fulfills https://savannah.gnu.org/bugs/?57756.

Also, show that the argument in the extendsyntax format is not optional,
as any command requires at least one argument. Also mention 'tabgives'
among the commands that are allowed in an included file.
Since the previous commit, nano exits from curses mode soon after
this message is printed, so that the user does not have any time
to read it or even see it.
When invoking the "internal" speller, leave curses mode while the three
programs in the pipe array are executing, to prevent 'hunspell' from
writing a long error message to the end of the status bar, making the
screen scroll, and thus messing it up. Now the error message gets
printed to the screen that nano was started up from, and will thus be
visible when the user exits from nano. (At least: it will be so on a
terminal emulator -- on a VT, nothing will be seen.)
This fixes https://savannah.gnu.org/bugs/?57728.
Bug existed since version 4.6, commit 4d77e0ad.
When at startup the user presses Cancel at the "open anyway?" prompt,
cancel the whole startup: quit. But when the user answers No, just
skip the file and continue starting up.
Don't bother looping until the 1024 bytes are read. Writing the lock
file takes just one shot too, and that is more important to get right.
Also, correct the type for the result of read(), so that -1 doesn't
get turned into a positive number, which would mean that any error
would get ignored.
It would be better if nano wrote the full filename into the lock file,
because that would be clearer when Vim displays its warning, but...
this is faster and will do for now.
(Nano should simply also store the full filename in the openfile struct,
so that get_full_path() needs to be called just once for each file.)
This addresses https://savannah.gnu.org/bugs/?57713.
The call of ferror() as parameter of a %s specifier was a mistake --
it returns a number, not a string. Avoid the problem by combining
two error checks.
The man page of fwrite() does not say anything about errno, but I guess
that the function calls write() and that the possible error numbers of
that function apply.
In theory it is now possible that fclose() fails and returns an error
that then masks an earlier error of fwrite(). But I can't be bothered:
lock files are not essential, and any errors that might occur are most
likely overlooked anyway because they are not displayed in red.
This fixes https://savannah.gnu.org/bugs/?57724.
Bug existed since lock files were introduced, in version 2.3.2,
commit bf88d27a.
Because ^C is needed for Cancel in most other menus.
