The cut and copy operations (^K and M-6) are different operations and
one should not add to the cutbuffer created by the other.
This fixes https://savannah.gnu.org/bugs/?56251.
Bug existed since version 3.0, commit 71f85937.
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.
The line numbers don't matter for the cutbuffer itself, but they matter
for the copy of the cutbuffer that is stored in an undo item.
This reverts commit 14140d52 from two hours ago.
This fixes https://savannah.gnu.org/bugs/?56245.
After extracting a line or region, the current line is always the one
where renumbering should start. And when ingrafting a buffer, it is
always the first ingrafted line where renumbering should start. The
'top_save' variable was indirectly getting set to those lines.
Also, renumber immediately after unpartitioning the file buffer, before
doing anything else.
Just like for deleting a word to the left, the mark should be ignored
also when deleting a word to the right.
This fixes https://savannah.gnu.org/bugs/?56241.
It doesn't matter whether the grafted text contains a newline or not.
It only matters whether the mark was before or after the cursor. When
it was after the cursor, the mark needs to be set to the bottom line of
the grafted text and its x coordinate needs adjustment; and when it was
before the cursor, the mark just needs to be set to the top line of the
grafted text.
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
strings.

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 around version 2.9.2.
All other options are off by default and can only be switched *on*
(either by a command-line option or a nanorc setting) -- there are
no command-line options to switch them off again. Except for the
--breaklonglines/--nowrap pair. So these need special handling.

When the file starts with one or more blank lines, the first paragraph
doesn't start on line 1.

Bug existed since version 4.0, commit ac8bd2a2.
It is still possible to use --jumpyscrolling on the command line or
'set jumpyscrolling' in a nanorc file, but a user will have to restart
nano when they decide they want chunky instead of smooth scrolling,
a decision that should be rather rare.
This frees up the M-S keystroke to be reused for toggling softwrap.
For relatively inexperienced users (as most users of nano probably are)
it is far better that nano produces POSIX text files by default, where
each line ends with a newline character. This means that these files
will "print" properly (not gluing the next prompt at the end of the
last line), tools will see and process each line of them, and, while
editing, adding text at the end is easier.

Instead of doing a check every time round the loop when it is useful
only the first time, duplicate a bit a code and do the check and its
related action beforehand.
Also, improve some comments.
Also, find_bracket_match() is only called when there is a bracket under
the cursor, so stepping forward will never go beyond the end-of-line,
so the central loop does not need to check for that.
Also, improve a comment and shorten another, change a 'for' to a 'while'
(as the end point is not known), and rename a parameter from a single
letter to a word.
The reading order must be predictable, otherwise things might get
colored differently from system to system.
This fixes https://savannah.gnu.org/bugs/?56012.
Otherwise the user could do something like
^R^X sed -i 's/a/surprise!/g' name-of-current-file <Enter>
and the file being viewed would be modified anyway.
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.
