c67ea1ffc1 undo: recompute the multidata when a piece of text is replaced
When a justification (or even a spell check) is undone or redone,
this might affect the matching of multiline regexes, so... schedule
a recalculation of the multidata in those cases.

This fixes https://savannah.gnu.org/bugs/?65426.
The issue was reported by `correctmost`.

Problem existed since version 6.3, commit 80c2000f.

a13cd6a177 execute: show "Older" and "Newer" in the help lines, to allow rebinding
Since commits c8363a0d and a75bf0a1 from seven years ago, the Execute
menu permits retrieving previously executed commands, but the help text
and help lines never showed the corresponding keystrokes.

Four years ago commit d3954901 made the Execute menu directly accessible,
but I preferred to not mention the ^P/^N keystrokes in the help lines,
to leave as much space as possible for the executable functions (added
in subsequent commits), thinking that no one would want to rebind those
keystrokes anyway, as the Up/Down arrows seem more logical and easier.

4ab80abb5e justify: recompute the multidata for paragraphs larger than the viewport
A freshly justified paragraph does not yet have any multidata,
and if this new paragraph has more lines than fit in the viewport
(minus one line for the cursor), then the line above the top of the
new viewport will be without multidata.  The coloring code cannot
handle this, so all the multidata then needs to be recalculated.

f37d097c1c rcfile: avoid crashing on an include path that is way too long
The `gnulib` globbing module apparently does not handle an overload

Problem probably existed since version 2.3.3,

191cf671be input: store keystroke in macro buffer only when about to interpret it
When the keystroke after the keystroke bound to `recordmacro` arrived
so quickly that the two got stored together in nano's keystroke buffer,
the main loop had not yet interpreted the `recordmacro` command and had
thus not yet set 'recording' to true, meaning that that second keystroke
would not get recorded.

Nano should record keystrokes into the macro buffer when fetching them
from its own keystroke buffer, not when fetching them from ncurses.

This fixes https://savannah.gnu.org/bugs/?65394.

ee1a1306e2 search: avoid crashing after searching a help text during a regex replace
Searching in a help text does not support using regular expressions,
so when 'inhelp' is set, do not free a compiled regex -- because if
there is such a regex, it belongs to a replacement session that is
about to begin.

4673e709b2 input: scroll on mousewheel events instead of moving the cursor
Translate mousewheel events into Alt+Up/Down key presses instead of
into plain Up/Down key presses, as the latter only start scrolling
once the cursor reaches the top or bottom.

Scrolling rather than moving the cursor is the standard behavior for
mousewheel events in GUI editors such as Gedit and Kate, as well as
in the mouse mode of terminal editors such as vim, joe, and mcedit.

190221c91c justify: set x = 0 for the undo item, for when using --cutfromcursor
When --cutfromcursor is active, 'current_x' needs to be set to zero when
doing a justification, so that the correct starting position gets stored
in the undo item.  (Without --cutfromcursor, the value of 'current_x'
does not matter.)

The issue was indirectly reported by `correctmost`.

Bug existed in this form since version 5.0, commit ae5a4ece.

Between versions 4.0 and 5.0, nano would not eat a line but would
instead crash when undoing a justification that was done with the
cursor away from the left edge.

77d74b5d81 input: flush the keystroke buffer upon any kind of error condition
This stops the execution of a macro or a string bind whenever something
unexpected happens, to prevent the waiting keystrokes from doing things
that were not intended.

Especially this prevents an infinite loop: when during the recording
of a macro the `runmacro` keystroke is typed in some menu (where the
keystroke is not bound), and the macro is later replayed in a way that
results in exiting from that menu before the `runmacro` keystroke gets
replayed...

18b37c980a new feature: option --modernbindings sets up more widespread key bindings
With --modernbindings, ^Q quits, ^F finds, ^B finds backwards, ^G finds
again, ^D finds again backwards, ^X cuts, ^C copies, ^V pastes, ^A sets
the mark, ^R replaces, ^O opens a file, ^W writes out a file, ^S saves,
^Z undoes, ^Y redoes, ^P shows the position, ^T goes to a given line,
and ^E executes.

Note that with --modernbindings ^Q and ^S are always bound, meaning that
--preserve / 'set preserve' is ignored.  This is necessary because ^Q is
an essential keystroke in the modern bindings.

Also note that these "modern bindings" are effective only in the main
edit window, not in the various menus.  In all menus ^C means Cancel,
and I can't think of a good alternative default keystroke for that
(in order for ^C to mean Copy).  And in a few menus ^V has a meaning,
and there is no good alternative for that either.  So... in the menus
the user has to use M-6 for Copy and ^U for Paste (and ^K for Erase --
Cut does not exist in the menus), like with the default bindings.

4a915b1ed5 input: avoid hanging after a 39-character paste on a VSCode terminal
The terminal in VSCode splits pastes into 50-byte chunks and can
thus split an escape sequence somewhere in the middle, resulting
in nano failing to recognize the end-of-bracketed-paste sequence
and thus hanging -- until another, different-sized paste is made.

Avoid this hang by interpreting any invalid escape sequence that
starts with "\e [ 2" as a truncated end-of-bracketed-paste.

(This will leave a spurious tilde after the 39-character paste,
which is not nice but... better than hanging.)

This works around https://savannah.gnu.org/bugs/?64996.
