Return immediately to editing mode when there are no messages for
the original file and the user does not wish to open any of the
included files that do have messages.
Also, reword the message that the linter gives then, and leave it
on the status bar (just like when Cancel is pressed).
The bindings for F1 to F12 are there for compatibility with Pico.
But Pico does not know anything about F13 to F16; for unknown reasons
they were added to nano. They seem hardly useful: normal keyboards
do not have the F13 to F16 keys, and very few people know that they
can "produce" those keys by holding Shift with F1 to F4. But typing
Shift plus F1 to F4 are just as "hard" as, for example, M-G and M-W,
so why anyone would want to use the first ones...? Especially since
many other functions of nano can only be accessed through Meta and
Control combinations.
Furthermore, F13 to F15 haven't been shown in the help texts since
version 2.3.3, so for more than four years no new user will have
learned about those keystrokes.
The rare user who wants these strange bindings can easily make them
herself.
The help lines will help differentiate this mode from normal editing
mode, and will tell the user how to jump to other messages.
This is a third step to address https://savannah.gnu.org/bugs/?54714.
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.
This fixes https://savannah.gnu.org/bugs/?54861.

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.
This fulfills https://savannah.gnu.org/bugs/?54654.

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.
