There are at least three other ways to achieve the thing that it did:
^End, M-/, and ^W^V. No need to have a fourth way by default.
For symmetry, also unassign the corresponding binding for M-|.
The 'cutwordright' function has gotten ^Delete as its default binding,
so the 'cutwordleft' function needs a default binding too -- also to
keep the items on the two help lines nicely paired. M-| was chosen
because it is close to the Backspace key on many keyboard layouts.
Print routines are not asynchronous-safe.
But... the only reason the call of kill() could return an error code
is when the relevant process has already terminated -- which is not
a problem, because that was the goal of calling kill().

As the help viewer is almost a normal buffer, commands that make sense
-- like searching backwards, and searching the previous occurrence --
should work in the help viewer too.
In addition, show all Search commands prominently in the help lines of
the help viewer, so that users are likely to notice them and will maybe
infer that they work in the editor itself too.
This fixes https://savannah.gnu.org/bugs/?54368.

Put "Where Was" in its place, to make the symmetry of ^W/M-W/^Q/M-Q
somewhat clearer. Also, conditionally reshuffle "Save File", to try
and keep menu items nicely paired.
The undo item for ENTER should record the file size *before* the amount
of auto-indentation whitespace is added to it.
This fixes https://savannah.gnu.org/bugs/?54344.

Bind the until-now unbound function 'cutwordright' to <Ctrl+Delete>.
The complementary function, 'cutwordleft', is not bound by default
because on many terminals the keystroke <Ctrl+Backspace> generates
^H -- the canonical ASCII backspace character. We cannot change the
existing action of ^H without upsetting some users.

To match the documentation and to match what the nanorc.nanorc
colors as valid.
In theory it would be possible to allow rebinding also F17...F63,
but nano does not recognize escape sequences for these high-order
function keys. As no one ever complained about unknown sequences
when pressing function keys, I am guessing that no one has these
high-order keys, or at least that no one uses them.

Instead of being entirely silent when ^] is hit after whitespace
or punctuation, report what is lacking -- similar to M-] saying
"Not a bracket" when the cursor is not sitting on a bracket.
This makes the ^] keystroke more discoverable.
This makes things symmetrical: ^W starts a forward search, ^Q starts
a backward search, M-W searches the next occurrence forward, and M-Q
searches the next occurrence backward.
The Tabs-To-Spaces toggle is moved to M-O, and thus the More-Space
toggle is no longer bound by default.
When using option -K on an xterm-like terminal, pressing <Shift+Del>,
<Alt+Del>, or <Ctrl+Del> would enter "2~", "3~", or "5~", respectively,
into the buffer. Now it will just report an "Unknown sequence".
The crawl needs at least five rows to be perceived as a crawl, and
the widest line is 31 characters (ignoring translations, which might
be even longer). Formerly, when only two or three rows were available,
nothing was shown at all, which was puzzling. So, better do the credits
only when there is room enough for them, and print a message otherwise.
When switching to a different buffer, don't just show its name but
also the number of lines it contains. This is useful extra info.
Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.
(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be. The info can still be seen when writing out
the file with ^O.)

Just like an <Esc> before a Ctrl+letter keystroke is ignored, an <Esc>
before an Alt+letter keystroke should be ignored too -- it should not
be interpreted as if the user had typed <Esc> <Esc> letter.
This fixes https://savannah.gnu.org/bugs/?54301.
Even when we don't act on most of these combinations, at least eat up
the whole sequence so the unknown keystroke doesn't enter things like
"3~" into the buffer.

Unlike glibc, which in getc() locks the file only when it is needed,
FreeBSD and Bionic libc will always lock the file, causing a massive
slowdown, as the system has to create and destroy a mutex each time
getc() is called.
Avoid that massive overhead by locking the file before starting to read
and unlocking it after reading is complete, and using getc_unlocked() to
read each byte. This makes reading on FreeBSD/macOS and Android anywhere
from 2 to 6 times faster, and on glibc roughly seventy percent faster.
This partially addresses https://savannah.gnu.org/bugs/?50406.

Also, consistently refer to Latin letters and ASCII characters
where needed, and document more accepted characters.
