The parameter was referenced in just one place. So, simply check for
the three relevant menus (and unrestricted mode) and be done with it.
This also has the pleasant effect that the menu name is now the first
parameter of do_prompt(), thus clearly indicating what prompt it is,
instead of having an opaque TRUE or FALSE value at the beginning.
Instead of burdening seven other calls of do_prompt() with a useless
parameter, just check for MGOTODIR in the appropriate place. It also
saves having to pass the parameter down through three more functions.
Instead of storing for each line the ordinal number of the first chunk
in that line, simply store the number of extra chunks in the line.
It now takes some more computation to actually draw the scrollbar, but
it saves a lot of computation when just inserting or deleting characters
(when using --softwrap and causing a change in chunk count).
This fixes https://savannah.gnu.org/bugs/?58510.
Bug existed since commit 6bccedb3 from two days ago.
Instead of creating a special Tools menu, add the five functions that
affect the whole buffer to the "Execute Command" menu. There is room
for these five functions there, and they kind of fit in because three
of them (Speller, Linter, and Formatter) actually invoke an external
command, and Full Justify could have been implemented externally, and
the destructive Cut Till End ought to have required a double keystroke
since the beginning.
In the past, when Speller and Linter and Formatter were all bound
to ^T (later ones taking priority), it was easier to exclude also
the formatter code when --disable-speller was used. But since the
formatter was reintroduced (in commit 34170611) and bound to its
own keystroke (M-F), this is no longer the case.
Just let all anchors disappear when doing an external spell check or
formatting or piping the buffer through an external command, because
leaving just a single anchor on the top line is useless.
This fixes https://savannah.gnu.org/bugs/?58273.
Bug existed since commit 732cf887 from one month ago. That code
causes an anchor to persist at the point where lines are removed.
When a single paragraph is justified, any anchor on any of its lines
gets moved to its first line. Let a full justification do the same
for each of the paragraphs.
This fixes https://savannah.gnu.org/bugs/?58272 in a better way.

Normally, when undoing an <Enter> that created automatic indentation,
the created whitespace should be skipped when rejoining the two lines.
In other words: take the data starting from tail_x in the second line.
But when the <Enter> occurred at the end of leading whitespace, then
that whitespace has disappeared from the original line and it should
be copied back in from the second line. That is: from x is zero.
This fixes https://savannah.gnu.org/bugs/?58108.

Bug existed since version 4.9, commit 1961c052.
This means that in most cases mark_is_before_cursor() is called twice:
once before get_region() is called, and once by get_region() itself.
This small duplication of effort is acceptable: the affected functions
are not time critical, and it makes the code shorter.
When the description of a keystroke starts with a very long word,
or when it does not contain any spaces at all (like for Chinese
and Japanese), do not break in the blanks before the description
but instead break IN the description, at the edge of the screen.
In other words: when wrapping a help text, do not consider blanks in
the first 17 columns to be blanks (unless it is a continuation line).
This fixes https://savannah.gnu.org/bugs/?57987.
Bug existed since version 4.8, commit 1486f32d,
when the wrapping of help texts was improved.
Only when the endpoint of the selection is actually IN a leading part,
then it should be advanced to include the whole leading part, so that
the succeeding paragraph will get the proper first-line indentation.
When justifying a selection from the middle of a paragraph, the first
line of both that selection and of the new paragraph after it should
get the same indentation as the first line of the original paragraph.
This fulfills https://savannah.gnu.org/bugs/?56308.
So that also the line after the newly made paragraph gets the
leading part that belongs to the start of a new paragraph.
This https://savannah.gnu.org/bugs/?57974.
Bug existed since version 4.0, since the justifying
of a marked region was introduced.
This assignment should have been removed in commit f5ac8c1e from
six years ago, as it became superfluous then. Later changes made
'cutbottom' become valid only when something had actually been cut.
Consecutive additions all happen on the same line. When automatic
hard-wrapping occurs, the ADD item is grouped together with an ENTER
item, and subsequent additions go into a new ADD item.
Either the marked region was cut (even when zero characters) or
the entire contents of the buffer were cut. In both cases this
is what needs to be piped to the command. That is: the contents
of the cutbuffer.
This fixes https://savannah.gnu.org/bugs/?57931.
Bug existed since version 2.9.8, commit f304b9ae,
when piping text to an external command was introduced.
Allow the creation of an empty CUT undo item (because the result of a
filtering operation may be empty), but then don't crash when undoing
such an empty CUT.
This fixes https://savannah.gnu.org/bugs/?57929.
Bug existed since version 2.9.8, when filtering was introduced.
Trying to do so would dereference a NULL pointer in copy_node().
This fixes https://savannah.gnu.org/bugs/?57915.
Bug existed since before version 2.2.0.
Also, remove two superfluous closings of file descriptors. The second
one has most likely already been closed by send_data(), by closing the
tube, and the first one will be closed by exiting from the process.
