Further down, the <Backspace> key is bound to do_page_up() for MHELP
and MBROWSER, so this earlier binding should exclude MBROWSER.
This partially fixes https://savannah.gnu.org/bugs/?54978.

Bug existed since version 2.9.2, commit 8581e702.
Set the Meta flag only for the regular Meta keystrokes: "M-" plus a
printable ASCII character. The special keycodes are unique and do
not need any extra flags to differentiate them.
This works for xterm, rxvt, Eterm, Konsole, and xfce4-terminal, which
generate "Esc [ 3 ; 3 ~", but not for urxvt, which generates one of
its double-escape sequences, "Esc Esc [ 3 ~".
Using --zap or -Z on the command line, or 'set zap' in a nanorc file,
makes the <Bsp> and <Del> keys erase selected text (a marked region)
as they do in some other editors, and without affecting the cutbuffer.
This fulfills https://savannah.gnu.org/bugs/?54837.

This function allows the user to "make space": annihilating lines or
regions while keeping intact for pasting the stuff in the cutbuffer
that was cut or copied earlier.

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.
