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.
This addresses https://savannah.gnu.org/bugs/?56189.
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.
