When something is spotlighted, it should survive a refresh of
the screen and an excursion to a help text, so the spotlight
should get painted whenever the edit window is drawn.
This fully fixes https://savannah.gnu.org/bugs/?54721.
It would result in having both <Delete> and <Backspace> behaving as
Backspace, which seems senseless -- unless the <Delete> key produces
ASCII DEL and --rebinddelete is needed to make it behave as Delete.
In the latter case it would make more sense if --rebinddelete made
both rebindings: ASCII DEL to Delete and KEY_DC to Backspace, like
it used to be in the distant past, before commit 79a33bb3.
The cursor can function as a reading aid for people with poor vision.

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.

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.

The new function, justify_paragraph(), takes a quote length and a
paragraph length (which it should get from find_paragraph()), and
runs the paragraph at (current, current_x) through justify_format().
Move some fragments out of the justifying loop, and adjust/clarify comments
to account for the changes. This will allow some of the code to be cleaned
up and simplified in the next commits.
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.

Only for BACK and DEL was the first call to update_undo() -- all other
types of action would call add_undo() first, so for them the action in
update_undo() would never be different, but the line number might have
changed (like for ENTER and INSERT), so for them exceptions needed to
be made, which was wasteful.
This addresses https://savannah.gnu.org/bugs/?54728.
The binding was made only to have *something* bound by default to the
'cutwordleft' function. But now that <Ctrl+Shift+Delete> is available
*and* visible in the help text, the M-| binding is superfluous.
When using the internal spell checker, the message gets overwritten
immediately by "Creating misspelled word list...", and when using
the external spell checker, nano immediately exits from curses mode
and thus the message disappears (when in a terminal emulator) or it
soon gets wiped by the spell checker (when on a Linux console), thus
creating a little flash on the bottom row, which we can do without.
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.
Assume that 'print' and 'exec' are statements when they are followed
by whitespace, and are functions otherwise. This does not highlight
"print'x'" nor "print{x}", but these statements are poor style.
