When inserting a file into the current buffer, the 'fmt' element will
already be set. When we avoid overwriting the current value of 'fmt'
(when it's other than UNSPECIFIED), we don't need to save and restore
the value when inserting a file.
When saving the buffer under a different name, it should by default
have the same format as the original file.
This fixes https://savannah.gnu.org/bugs/?60278.
Bug existed since version 2.6.0, commit 0293eac1.
This improves the fix for https://savannah.gnu.org/bugs/?60269,
by not dropping error messages that happen before a buffer is opened.
This basically reverts commit b63c90bf from a year ago, except that
it now always deletes the created buffer when the user does not want
to override the lock file, also when it is the only buffer.
Set the 'format' of a file only when it has been fully read in,
so that this field can be used to indicate that any later error
message cannot be meant for this buffer.
This fixes https://savannah.gnu.org/bugs/?60269.
Bug existed since commit 6bf52dcc from yesterday.
Make sure there is an 'openfile' record before trying to save an
error message in this record.

Labels may contain digits (after the first character).
And the colon after "default" should not be colored.

When opening multiple files and some of them had an error, only the
first message was shown and the others were lost -- indicated only
by three dots. Improve upon this by storing the first error message
for each buffer and showing this message when the buffer is first
switched to.

That is: reserve for the current line and current character the number
of positions needed for the total number of lines and characters, and
reserve two positions for both the current column and the total number
of columns. This will keep all nine numbers in the output in the same
place -- as long as there are no lines with more than 99 columns. In
this latter case there will still be some jitter, but all-in-all the
output is much stabler than it was.

The number of lines in a group is the difference in line numbers
between the last line and the first line *plus one*.
This fixes https://savannah.gnu.org/bugs/?60104.
Bug existed since version 2.9.0, since indenting and unindenting
became undoable, and commit f722c532 formed a part of that.
Allocating it again would leak the existing space.

Bug existed since version 5.6, commit 1fdd23d3.
When the version number is a trio, the version string will occupy
ten bytes and the terminating NUL byte would not be written (which
was not a problem as byte 12 of the lock data is zero anyway).
But it's better to not have the compiler complain, so allow writing
the terminating NUL byte outside of the ten bytes reserved for the
version string.
This fixes https://savannah.gnu.org/bugs/?60149.

Bug existed since version 5.6, since a special color for highlighting
search matches was introduced in commit 87fe73dd.
Full justification (like justification of a selection) is probably
a rather rare action -- and possibly even an unintended action --
so it's good to give feedback about what happened also when using
the minibar.
When a line is marked as JUSTONTHIS, there should be no second start
match on that line, because otherwise the line would have been marked
as STARTSHERE (unless there is also a second end match -- but it's
fine to do unnecessary refreshes in this unlikely case, as long as
the necessary refreshes are made).
This fixes https://savannah.gnu.org/bugs/?60074.
Bug existed since version 2.5.0, but has been masked (for the C syntax)
by unnecessary refreshes since version 4.1, commit c9605e73.
When a line is marked as NOTHING, then the existence or the appearance
of an end match is irrelevant: there is no unpaired start match, so no
recoloring would occur, so there is no need to refresh.
When a line is marked as WOULDBE, then the existence or the appearance
of a start match is irrelevant (for the lines after the first WOULDBE
line): there already is an unpaired start match, so another one will
not change anything, so no refresh is needed. Only the appearance of
an end match would recolor things and thus require a refresh. However,
start and end regexes could match the same thing, so an end might get
misinterpreted as a start. So the rule has to check for the absence
of both a start and an end match, like for WHOLELINE.
This addresses https://savannah.gnu.org/bugs/?60072.
A step forward needs to be forced not when both start match and
end match have zero length, but when the "full match" (all text
from the start of the start match to the end of the end match)
covers zero bytes. In other words: the start and end match are
both of zero length AND are at the same spot.
Now that a search match gets highlighted, the unsuspecting user might
think that the text is selected, because it is colorized the same way
as selected text. Avoid this by colorizing a highlighted search match
with its own specific color, black on yellow by default.
In addition, suppress the feedback for M-C also when --minibar
isn't used, as the feedback obscures the effect of the toggle:
showing information about the cursor position on the status bar.
This fixes https://savannah.gnu.org/bugs/?60019.
Bug existed since commit 7545eb5b from one week ago.
Highlighting an occurrence is so much clearer than just putting the
cursor on it. People seem to like it. So let's make this how nano
behaves by default.
Take two conditions that are relevant only for a rather unlikely case
(a start match without a corresponding end match) out of an inner loop.
Give the case its own, dedicated loop.
When leaving the multidata unset (as was done until now) and the
end match is offscreen, then this could lead to miscolorings later
when jumping over this end match instead of scrolling past it.
This fixes https://savannah.gnu.org/bugs/?60012.
Bug existed since before version 2.1.10.
When a large piece of text or code is pasted or inserted, it could
contain matches for start= and end= regexes, and backtracking from
the current screen could mistake an end for a start and could thus
miscolor things. Avoid this by recalculating the multiline cache
for pastes and insertions that cover more than a screenful.
This fixes https://savannah.gnu.org/bugs/?59982.
Bug existed since version 2.6.0, but existed also before 2.4.3.
This allows having an even leaner interface, and gives the M-C toggle
an appropriate function (instead of leaving it a "dead" keystroke).

If a paste (or insertion) is more than a screenful, it will not set
'focusing' to FALSE. In that case, and when line numbers are already
active, then 'focusing' should be kept set to TRUE, despite it getting
set to FALSE by ensure_firstcolumn_is_aligned(). That latter action
is meant to cushion size changes of the edit window, but in this case
the large paste (or insertion) should trump the size change.
This fixes https://savannah.gnu.org/bugs/?59981.
Bug existed since version 2.8.3, commit 2b385478.
Commit 43d94692 fixed a miscoloring bug [1] by doing proper backtracking
for multiline regexes. But this change also solves an older miscoloring
issue [2] without needing to recalculate all the multiline data. So...
just drop the old fix. (This isn't perfect: it's probably possible to
cook up a replacement scheme where things get miscolored, but... until
then, this is good enough.)

Also, there is no need to set 'refresh_needed' in do_replace_loop(),
because each replacement prompt will call edit_refresh() anyway, and
the functions that call do_replace_loop() will set it afterward.
