This avoids some warnings when compiled with -pedantic:
ISO C forbids comparison of ‘void *’ with function pointer
ISO C forbids empty initializer braces
When the active syntax contains a comment command that specifies the
empty string, this should override the default comment of "#" and
should disable the Meta-3 keystroke.
To achieve this, the comment string is now set by default to "#" for
all syntaxes, so that it will be set when no comment command is given
(including for the "none" syntax), and is unset only by explicitly
specifying «comment ""» in a syntax file.
This fixes https://savannah.gnu.org/bugs/?51355.

When also --nohelp is active and the terminal is so narrow that the
message that --constantshow displays on the bottom row does not fit,
this causes the cursor to be pushed "offscreen". Some terminal
emulators don't handle this case correctly, and leave the cursor
in an invisible or mistaken position. Compensate for this by
moving the cursor back to the start of the row.
This fixes https://savannah.gnu.org/bugs/?51335.

The extra variable is not needed, because when having read from
standard input, the filename will simply be empty. It will not
be empty for any other file that was read.
A recent change (8dffb00f) removed this ability. This change restores
it, and also allows reading from standard input multiple times -- maybe
not useful, but it works.
Also when a dash is the first "file" mentioned on the command line,
nano should show this buffer at startup and not the next.
This fixes https://savannah.gnu.org/bugs/?51207.
In the tiny version, Ctrl+Left and Ctrl+Right are available only
in the editor itself and in the file browser.
This fixes https://savannah.gnu.org/bugs/?51173.
The old praxis of calling total_refresh() upon a SIGCONT was confusing,
because the screen would look as if nano had returned from suspension,
but in fact the shell was still active.
Instead of calling total_refresh(), put a no-op key into ncurses' buffer,
so that, when nano actually does return out of suspension (through 'fg'),
this key will be read and discarded, upon which nano will go sit and wait
for the next key, just before which it calls doupdate(). The latter is
all we need to get the entire screen restored.
This also fixes https://savannah.gnu.org/bugs/?51131 for "tiny".
When receiving a SIGCONT, don't call regenerate_screen() directly
but act as if a SIGWINCH occurred. Also insert a dummy key, and
thus let the relevant input routine redraw the relevant subwindows.
Use KEY_F0 as the dummy key, as both Ncurses and Slang know it, and
it should normally do nothing at all.
This fixes https://savannah.gnu.org/bugs/?51124.
When we are in the file browser, browser_refresh() will take care of
redrawing the title bar and the file list, so total_refresh() should
leave those two subwindows alone in that case.
This fixes https://savannah.gnu.org/bugs/?51147.
Achieve this by making the suppression flag global, so that we can
just reset it instead of making an improper call of do_cursorpos().
This fixes the secondary part of https://savannah.gnu.org/bugs/?51134.
It is no longer necessary to assign up() and down() separately for
the help viewer because by now the movement keys have been sorted
in order of ascending stride also in the main menu.
The two string definitions are relocated just to reduce the number
of #ifdefs.
Apparently the curses on SunOS is less forgiving than the one on GNU.
Or rather: delwin(NULL) should just return an error, it shouldn't crash.
This fixes https://savannah.gnu.org/bugs/?51053.
