Now M-D will report 0 lines instead of 1 line for an empty buffer, and
will match the output of 'wc --lines' as long the file is a POSIX file.

Bug existed since before version 2.1.10.
For this one quick switch back and forth there is no need to report
anything on the status bar nor to update colors and such. In this
case, those things are just a waste of time.
No one ever reported seeing the message that was removed in commit
c039aaad one month ago, so most likely the code is correct and nano
never calls line_from_number() with a non-existent line number.
For both an integrated and an external spell check, fake the Shift key
being held so that (when the cursor is moved by a changed length of a
word) a Shift-selected region is not unexpectedly cancelled.
This fixes https://savannah.gnu.org/bugs/?56365.
Don't bother checking for an error from sigaction(), because the only
things it could error out for is when it is passed an invalid signal
(which SIGINT isn't) or oldaction/newaction would point to memory that
is outside of nano's control (which is obviously not the case).
Also, the setup of signal handlers during startup does not check for
errors, so why do it here?
If functions deeper down would put up some message on the status bar,
it should not be cleared. The chance that messages from a spell-check
program stay onscreen is minute: the edit window is fully refreshed,
the status bar is fully drawn, and the help lines (if there are any)
are redrawn. Only the title bar is not refreshed, but the chance that
an error message has spilled onto the top row... And anyway, the
spell checker should not print any error messages at all.
The integrated spell checker does not use regular expressions, and
'refresh_needed' is set to TRUE anyway, so the tidy_up_after_search()
call there is effectively a no-op.
The lines from the cutbuffer will be renumbered when it matters: when
they get pasted.
The only place that used the numbering of (a copy of) the cutbuffer
(the updating of an undo item) already iterates through its lines.
Just add a counter there instead of making use of the line numbers.
All extractions are done into the cutbuffer, so it is pointless to pass
'cutbuffer' and 'cutbottom' in and back out as parameters all the time.
Just use those global variables directly.
Also, rename the function as there is no longer a buffer among its
parameters.
The 'cutbottom' variable is only ever used when cutting or copying
consecutive lines: for appending the current line to the already
existing lines in the cutbuffer. As soon as some other operation
is performed, 'cutbottom' becomes irrelevant, it could be set to
anything, it doesn't matter: the pasting of the cutbuffer does not
use the value of 'cutbottom', nor does any other operation.
Avoiding this leak is more trouble than it's worth: invocation_error()
will be called seldomly, and when it is called, the user will probably
quickly exit from nano to fix things.
Also declare the speller functions as const again, so they don't give
the impression that their result can be freed.

Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.
You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.
In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

Most of the returned error messages are fixed strings, not allocated

Bug existed since version 4.1, commit f645009a.
When automatic hard-wrapping causes some piece of a line to be pushed
to the next line, then a separating space needs to be added at the tail
of this piece only when this piece actually gets prepended.
This fixes https://savannah.gnu.org/bugs/?56185.
Bug existed since version 2.9.2, commit 29f7654a.
When typing a space causes both the succeeding word and the cursor to
be pushed to the next line, then this space (and any contiguous ones)
does need to be snipped (when --trimblanks is in effect).
This fixes https://savannah.gnu.org/bugs/?56180.
Bug existed since version 2.9.3, commit 91073be4.
Do the same as in the previous commit: re-evaluate the start of the
viewport when lines that are located above this viewport may have
changed. This is relevant when softwrap is on.
When only the trailing chunk of a line is displayed on the top row of
the screen, and the unindenting of this line leads to a reduction in
the number of chunks, then the starting point of the viewport needs
to be re-evaluated. For simplicity, do this always when something is
unindented.

Bug existed since version 4.0, commit ac8bd2a2.
The word "buffer" in relation to undo has been confusing to translators.
Also, drop the exclamation mark, as there is nothing important or urgent
about these messages.
Because somehow something goes wrong when SIGWINCHes are handled while
reading from a pipe.

Bug existed since version 2.4.2, commit 75d64e67.
Some commands can take a little while to execute; showing just the prompt
during that time could give the impression that nothing is happening.
This addresses https://savannah.gnu.org/bugs/?56041.
When nano was configured with --enable-tiny --enable-speller, the
block_sigwinch() function should be available, to mask SIGWINCHes
during a spell check.
The blocking is needed only during the wait(), so unblock SIGWINCH
again right after the wait() -- also to have the unblocking before
a possible error exit.
Somehow a SIGWINCH pushes nano past the wait() in do_alt_speller(),
even though the external spelling program hasn't finished.

by reverting commit 1f39f60b.
Bug existed since version 3.2.
Since commit 4c6ec637 from about half a year ago, the 'action' parameter
of update_undo() is unused. Verify that this parameter matches the type
of the item at the top of the undo stack, so that in another half year
the parameter can be safely removed.
When the mark is off, initialize not just 'bot_x' but also 'top_x'.
This fixes https://savannah.gnu.org/bugs/?55898.
Bug existed since the justifying of a marked region was introduced,
four days ago, with commit f7f5514e.
This matches Pico's behavior. However, Pico doesn't add the quoting +
indentation to the line in which the selection ends, but this is wrong,
so nano does add it. Also, Pico doesn't account for partial quoting +
indentation at the start or end of a selection, but this is wrong, so
nano does.
Unlike a regular paragraph, marked text may have different quotes and
more than two types of indentation. Handle this by replacing deviant
quotes with the quote of the first line, and deviant indentation with
the indentation of the second line.
This is modelled after Pico's behavior. However, Pico won't do anything
if you do a full-justify while the mark is on. But this is unnecessarily
limiting, so, when the mark is on, nano will handle a full-justify and a
plain justify the same.
This currently does not handle the lead (quoting + indentation) in
justified selections, does not put mid-line justified selections onto
separate lines, and does not strip whitespace after the lead in justified
selections, the latter two of which Pico does. These behaviors are
forthcoming.
concat_paragraph() concatenates a paragraph into a single line, and
rewrap_paragraph() rewraps that line into multiple lines again.
These two will be needed when the justifying of marked text is added.
Instead of passing 'quote_len' to these functions, calculate it directly
in them.
This will be needed when the justifying of marked text is added. When
unmarked text is justified, it is a single paragraph and by definition
has a uniform quoting part. But marked text may be a jumble of lines
that have different quoting parts.
When doing replacements or fixing misspelled words, and edit_refresh()
is called to highlight the relevant word, then the current menu can be
anything from MREPLACEWITH, MYESNO, MSPELL, or MMAIN. Make sure it is
always set to the latter just before calling edit_refresh(), so that
display_string() will use the full length and the word gets properly
highlighted.
