Move the unsetting of some options further down, to prevent the user's
nanorc enabling things that are not permitted in restricted mode.
Also, in restricted mode, suppress error messages about functions not
being present in the requested menus, so that a nanorc that is valid in
normal mode does not cause unnecessary messages when using --restricted.
This fulfills https://savannah.gnu.org/bugs/?54732.

In the past, SIGWINCHes were responded to immediately (which was madness),
but since commit 75d64e67 all a SIGWINCH does is set a flag so that, when
the time comes to update the screen, nano knows the dimensions may have
changed. The mentioned commit removed most blockings and unblockings of
SIGWINCH, but not this one.
As the statusbar() function will write the position directly to the
terminal when not in curses mode, the final part of this position
message will seem to be after the prompt when exiting from nano.
The cursor position will get written correctly to the status bar
anyway, because returning from suspension enters a fake key into
the keyboard buffer, and this key elicits an update of the display.
This fixes https://savannah.gnu.org/bugs/?54639.

Bug existed since version 2.4.2, commit 75d64e67.
Most of these toggles just change the appearance of things, and
all of them are harmless -- none of them modify the contents of
the buffer.

Bug existed since version 2.9.4, commit 54103d8e.
(The offending commit meant in the previous commit was 60f1090d.
My mistake.)
When curses gives no code for Ctrl+Shift+Delete, do not fall back
to KEY_BACKSPACE, because then ^H and/or <Backspace> get bound to
'cutwordleft'.
This fixes https://savannah.gnu.org/bugs/?54642.
Bug was introduced with version 3.0, commit e6429e78.
On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings. Weird, but
wonderful, because the ideal behavior.
Also ensure that <Shift+Delete> always does a Backspace.
This makes that we have the following set of "congruent" keys:
<Tab> moves text to the right,
<Shift+Tab> moves text to the left,
<Delete> "eats" a character to the right,
<Shift+Delete> "eats" a character to the left,
<Ctrl+Delete> "eats" a word to the right,
<Shift+Ctrl+Delete> "eats" a word to the left.
Bind the until-now unbound function 'cutwordright' to <Ctrl+Delete>.
The complementary function, 'cutwordleft', is not bound by default
because on many terminals the keystroke <Ctrl+Backspace> generates
^H -- the canonical ASCII backspace character. We cannot change the
existing action of ^H without upsetting some users.

When switching to a different buffer, don't just show its name but
also the number of lines it contains. This is useful extra info.
Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.
(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be. The info can still be seen when writing out
the file with ^O.)
This addresses https://savannah.gnu.org/bugs/?54047.
Otherwise the first line of a multiline /*...*/-comment would be
seen as quoted and thus *not* as the first line of a paragraph.
In the code, use "/{2}" to prevent the remainder of the line
getting colored as a comment.
In the past, the argument could be either a regex or a literal string,
so the wording was kind of vague. But nowadays we can count on having
regex support (through gnulib), so be more precise in the description.
The tiny version contains much less code, so is less likely
to crash. And the users most likely use it for very simple
and short editing jobs, making the chance of a crash still
smaller. So the handler would just be bloat.
When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,
nano will stop at the ends of words instead of their beginnings.

Upon a segmentation fault or an abort signal, instead of crashing,
losing all changes, and leaving the terminal in curses mode, nano
now calls die(), to save any changed buffers and to restore the
terminal to a usable state.
For the remote chance that nano segfaults in die(), the handler for
SIGSEGV and for SIGABRT is reset to its default value as soon as the
signal fires, to prevent a crash-handler loop.
Since a core dump is usually more helpful for debugging, the crash
handler is not included in a debug build.

Also, add a period after the "Read nn lines" message, and
don't let the next shell prompt overwrite this message.
