Ask ncurses for the codes for the Shift+arrow keys, so that also
<Shift+Up> and <Shift+Down> can be recognized, for which ncurses
doesn't have standard codes.
This fixes https://savannah.gnu.org/bugs/?54790.

This allows running the speller (default binding: ^T) also on files for
which a linter has been defined. This makes it possible to spell check
comment blocks in source files, for example.
This fulfills https://savannah.gnu.org/bugs/?54711.

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.
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.
Since the last version, the user can filter an entire buffer through
an external command. This external command can also be a formatting
program, so there is no longer any need for this specific and special
formatter command.
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.
When executing a command, it is now possible to pipe the entire buffer
(or the marked region, if anything is marked) to the external command.
The output from the command replaces the buffer (or the marked region),
or goes to a new buffer.
This fulfills https://savannah.gnu.org/bugs/?28993,
and fulfills https://savannah.gnu.org/bugs/?53041.

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.

When just scrolling and the cursor does not need to change position
(that is: it is not on the first or last row of the edit window),
then edit_scroll() has handled everything and there is no need to
additionally redraw anything or update 'placewewant'.
