67873e961b cutting: cover the corner cases where cut commands do not cut anything 
Give the correct feedback in those cases and do not add an undo item.

This fixes both parts of https://savannah.gnu.org/bugs/?55396.

50e8f8aab9 cutting: give feedback when otherwise nothing happens 
This makes the cutting and pasting keystrokes somewhat discoverable.

ce6f320947 cutting: when ^K does not actually cut anything, do not add an undo item

4104376e7c tweaks: rename a variable, elide another, and adjust two comments 
Also, adjust the type of a parameter to 'size_t', as it is a
character index.

16c20ad873 tweaks: move the character/word-deletion functions to a better location 
Having all the cutting and deleting functions together in one file
kind of makes sense.

329b82d284 undo: set the correct file size for a redo of a character deletion 
The reduced file size should be stored not just when joining two lines
but also when simply a character in the middle of a line is deleted.

This fixes https://savannah.gnu.org/bugs/?55352.

Bug existed since version 2.5.0, commit 66e21416.

798695ff1e utils: retire the fixbounds() function -- it is no longer needed 
All tested systems (FreeBSD, NetBSD, OpenBSD, Alpine, and Ubuntu)
support the GNU-style word boundaries (\< and \>), either natively
or through using the regex module from gnulib.

If this change breaks regexes containing \< or \> on your system,
please report a bug: https://savannah.gnu.org/bugs/?group=nano

This addresses https://savannah.gnu.org/bugs/?55207.

125cc0cd74 tweaks: elide a tiny function by making a variable global 
And in the bargain it makes things clearer, because the name
cutbuffer_reset() is misleading.

7e152f2a48 undo: when undoing a cut, remove also the magicline if it added one 
Reuse the WAS_FINAL_LINE flag to signal a cut that added a magicline,
for both a marked cut and cut-to-eof.

This fixes https://savannah.gnu.org/bugs/?55305.

dc99610c36 docs: reword and reshuffle the description of --rawsequences 
It's not just about the numeric keypad, but about the interpretation
of all editing keys (arrows, Home, End, PageUp, PageDown, Insert, and
Delete), of the escape sequences that they produce.

d3c0fe3923 options: make --rawsequences disable --mouse, to prevent entering junk 
When using --raw, ncurses does not catch and convert any mouse event,
and thus the coordinates of a mouse click would get inserted into the
buffer as seemingly random characters.  So, let --rawsequences override
and disable --mouse, to prevent the accidental entering of junk.

This fixes https://savannah.gnu.org/bugs/?55303.

67c69b2298 options: rename long version of -K from --rebindkeypad to --rawsequences 
To better describe what it does, and to have full contrast with the
--rebinddelete option: the latter can now be shortened to --rebind
without getting a conflict, and --rawsequences can be abbreviated
to simply --raw and still make sense.

0946153b47 tweaks: hard-bind ASCII DEL in a slightly more economical way 
And in the bargain get rid of a duplicate help-text entry for
either "Del" or "Bsp".

9b2c2697cb options: make -d (--rebinddelete) work without -K (--rebindkeypad) 
When the terminfo selected by TERM does not match the terminal and
the <Delete> key behaves the same as <Backspace> (deleting leftward)
or the <Backspace> key behaves the same as <Delete> (deleting without
moving the cursor), then using just -d or --rebinddelete should make
the deviant key behave correctly again without affecting the other.

55c52c50d0 bindings: hard-bind ASCII code 0x08 (BS) to the backspace function 
ASCII code BS should always do a backspace, also on systems where the
"^H" string gets redirected (for rebinding purposes) to KEY_BACKSPACE.

This fixes https://savannah.gnu.org/bugs/?55247.

77bd8c2630 tweaks: swap the names of the variables 'wrap_at' and 'fill' 
Now 'fill' contains the original specified value,
and 'wrap_at' the column that 'fill' translates to.

3121ee4b2e options: stop recognizing and mentioning --quiet and 'set quiet' 
Those options have been a no-op and obsolete for over a year.

Just continue to accept and ignore -q, for some "compatibility"
with Pico.

3a170d2c3e rcfile: when rebound, DO unbind a keystroke from its earlier function 
When not unbinding it from its earlier function (in the same menu),
it would result in showing the keystroke twice in the help text.

This fixes https://savannah.gnu.org/bugs/?55239.

Bug was introduced a month ago, by commit f81d174f.
