When --view is used without --ignorercfiles, the user could view
other files anyway if they had 'set multibuffer' in their nanorc.
So, just make this the default when --view is used, also because
"multibuffer" cannot be toggled once nano is running in view mode.
When the viewing of other files in view mode should not be allowed,
one should now additionally use --restricted.
The 'wrap_at' variable, removed in commit e90b7cf4, is actually needed
to store the original value of the --fill option when it is negative.
Otherwise, changing the screen width will not update the wrapping point
properly.

The ^P and ^N keystrokes for Older and Newer are relevant to searching
and should be visible in the help lines. FullJustify, paragraph jumps,
and top/tail jumping are there only for compatibility with Pico but
don't make any sense there, so it's no problem if they are pushed out
of view.
Rename not only the bindable functions, but more importantly reword the
tags that are shown for ^P and ^N in the help lines: "Older" / "Newer",
because these are clearer and not awkward abbreviations.
When using --view --multibuffer --restricted, it is the latter option
that forbids reading in another file, so that is what the status bar
should say.
This fixes https://savannah.gnu.org/bugs/?54824.
Bug existed since version 2.9.5, commit 8b8c6bb8.
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.
This fixes https://savannah.gnu.org/bugs/?54790.

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.
