Constants that consist of a single character are valid too.
And a lone hash character on a line by itself also.

This probing has been changed four times in the past:
git log --grep get_wch
In March 2005, commit 2161fa62 changed the probe from get_wch() to
wget_wch(), reasoning that "get_wch() might be a macro instead of
a function". (Four months earlier, commit 3ba9c351 changed it
from addwstr() to wget_wch(), probably for the same reason.) But
three months later, in commit 25799f68, the probe gets changed to
get_wch() again, because "it's a more generic function"...
It seems clear that the non-macro argument is the stronger one.
See the NOTES section in 'man get_wch' for its possible macroness.
This addresses https://savannah.gnu.org/bugs/?58997.

This is the opposite of what 'ls' does in a UTF-8 locale, but nano
has never followed the collating rules of Unicode (uppercase after
lowercase, ignoring punctuation, and so on) -- it would be strange
to change that now.
Until now, nano left such equivalent names unsorted, in a seemingly
random order.
This fixes https://savannah.gnu.org/bugs/?59059.
Bug existed since before version 2.0.6.
And mention that a background color does not work on libvte before 0.55.
To find out the version of libvte on your system:
ls -R1 /usr/lib | grep libvte | grep 00 | grep -o "0\..."
Do the same what the normal "research" code does: if nothing was
searched for yet during this session, and there is a history of
search items, then search for the last item in that history.
Make case-insensitive searching in a UTF-8 locale eight times faster
when the actual characters involved are plain ASCII.
This makes us faster than 'less', and as fast as Vim and Emacs.
The disadvantage of this change is that searching for a string that
begins with a multibyte character is nearly ten times slower than
searching for one that begins with an ASCII character. This may be
unsettling when searching a huge file first for a simple ASCII string
and later for a UTF-8 one. Doing this second search, the user might
get impatient: "Why is it taking so long?"
(This patch fell through the cracks four years ago, when I worked on
the searching code. It sat in a branch on top of other changes that
I never applied because I made different improvements. The speedup
at the time, on that machine, was only around sixty percent, though.
But measuring it now again on the same machine, it clocks in at an
82 percent reduction with -O0 and an 87 percent reduction with -O2.)
Those casts are redundant, and sometimes ugly. And as the types of
variables are extremely unlikely to change any more at this point,
the protection they offer against miscompilations is moot.

The two functions findnextstr() and do_replace_loop() do not change
or even touch 'last_search', so there is no need to save and then
restore its value when doing corrections of misspelled words.
Storing the orientation of the marked region beforehand is not needed,
as this orientation is readily available also after the justification.
(By the way, cursor and mark need to be swapped after justifying
a backward-marked region because the rule is that the cursor gets
placed *after* the justified paragraph. Maybe that should change?)
The most likely reason for stat() returning -1 is that the file
does not exist. And an absent positionlog file is not an error.
(In some cases it is, like immediately after writing the file,
but even then we don't want to complain, because it may have
been some other process that deleted the file straightaway.)
This fixes https://savannah.gnu.org/bugs/?58993.
Bug existed since version 5.0, commit fcb9e58b.
This ability was lost in commit 92298349 from two hours ago, which
bypasses the keystroke buffer and its integrated screen resizing.
This new implementation is better than it was before, because it
responds almost instantly to a resize instead of with a delay of
up to a second.
(Still, this does not allow a full escape sequence to be used as
the Cancel command, but I think that is an acceptable limitation,
because 1) nobody ought to be using --rawsequences, and 2) very
few people will bind Cancel to something like F3 or Ins.)
This improves the fix for https://savannah.gnu.org/bugs/?58825.
When checking (during a Search command) whether the user has pressed
the Cancel keystroke, look at ncurses' input stream directly instead
of at nano's own keystroke buffer, because the latter may contain the
copied keystrokes of a macro and we don't want to discard those.
(This does not yet allow a Meta keystroke to be used for Cancel, but
the next commit will fix that.)
This fixes https://savannah.gnu.org/bugs/?58825.
Bug existed since version 2.9.0, since the macro was introduced.
First mention the three main 'pieces' of the editor: Editing window,
Help viewer, and File browser. Then mention how to change settings:
with the toggles or with nanorc files.
There is no reason to deselect the region, as nothing has changed.
(This also retains the shift-selected region when a non-shortcut key is
typed in view mode, which makes sense, as again nothing was changed.)
This fixes https://savannah.gnu.org/bugs/?58980.
Bug existed since version 4.9, commit 0ed62e84.
Replace an obsolete question that doesn't have a good answer: setting
TERM to vt100 is unlikely to make the more complicated keystrokes work,
which are the ones that are most likely not to work.
When keypad() is set to FALSE, like for verbatim input, ncurses is
not waiting its fifty milliseconds after an ESC to see if another
code will follow it, so nano itself will have to pause a little.
Otherwise 'solitary' could get set to TRUE when in fact the ESC
is followed very closely by another code.
This fixes https://savannah.gnu.org/bugs/?58955.
Bug existed since version 2.6.2, commit f2150d3f.
Also when each character is just one byte, parse_verbatim_kbinput()
can produce two bytes; plus the terminating NUL that is three bytes.
This fixes https://savannah.gnu.org/bugs/?58959.
Bug existed since version 4.9, commit 03d296eb.
For installing and using nano, those two Changelogs are useless,
and for inspecting the history of nano, 'git log' is much better.
Only the most recent Changelog is somewhat useful for some users,
for walking in some detail through the changes that were made in
the last few versions.
