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.
This fixes https://savannah.gnu.org/bugs/?60268.
Bug existed since commit ede64d7e from yesterday.
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.

Bug existed since version 5.6, since a special color for highlighting
search matches was introduced in commit 87fe73dd.
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.
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.
This allows having an even leaner interface, and gives the M-C toggle
an appropriate function (instead of leaving it a "dead" keystroke).

Backtracking from the first row is needed in case a start match was
added recently somewhere offscreen and the user jumped to the current
location (instead of scrolling) so that the CWOULDBE markings did not
reach the current lines.
Also, search for an end match only for the first screen row. For the
other rows, rely on the CENDAFTER, CWHOLELINE, and CWOULDBE values to
indicate whether there *is* an end match (the first two values) or not.
This saves considerable time when there is no end match in the large
remainder of a buffer: it will search in vain for the end match just
once, instead of for every row of the screen.
This fixes https://savannah.gnu.org/bugs/?59948,
and addresses https://savannah.gnu.org/bugs/?59945.
Bug existed since version 2.7.5, commit b3bcc8ee.
Like the other two fragments that advance over a zero-length match,
also this fragment should avoid the possibility of stepping beyond
the end of the line.
When a zero-length match is beyond the width of the screen, there
is no point in continuing evaluating the rule, so the check for
"offscreen to the right" needs to come first. The check for a
zero-width match needs to come second because otherwise we would
get stuck on such a match when it is offscreen to the left.
When the match of a coloring regex is beyond the width of the screen,
there is no point in continuing to evaluate the regex for the rest of
the line, because any other matches will be offscreen too.
This will save some time when there are several overlong lines.
A syntax has on average a dozen coloring rules, but on average maybe
three or four pieces of text (rough estimate) in a line get painted.
So, on average, it is cheaper to call wattron() and wattroff() only
when actually coloring a piece of text, instead of calling wattron()
before starting to evaluate each rule and wattroff() after finishing
its evaluation.
When reaching end-of-line after having found a zero-width end match,
nano should not continue at 'seek-an-end' but instead at 'step_two':
going on to seek a start match in the current line.
(There is no bug report, because I cannot figure out how to trigger
this issue and cause nano to misbehave. The problem was found while
reviewing the comments.)
Bug existed since commit 9a4a5454 from four years ago,
but the behavior was poorer before that commit.
An invalid UTF-8 starter byte should not be represented in the same way
as a valid Unicode character.
This fixes https://savannah.gnu.org/bugs/?59832.
Bug existed since two weeks ago, since the mini-bar code was merged.
The first byte of a multi-byte UTF-8 sequence must be in the range
0xC2...0xFF. Any other byte cannot be a starter byte and can thus
immediately be treated as a single byte.
When space is too tight to show all three elements, show the report on
the number of lines in preference to the current location and character
code. The latter two will be shown again upon the next keystroke, so
there is little harm in hiding them for a moment.
Having a block cursor present when highlighting a match...
does not look nice. So... hide the cursor until the next
keystroke, unless --showcursor or 'set showcursor' is used.
Remarks are about unsurprising things but it's good to give feedback
on them; "mistakes" are unexpected things, and get colored like an
error; and information is something that the user requested and thus
needs to stay on the status bar until the next keystroke.
For some reason, calling halfdelay() undoes the ISIG mask.
So, mask keyboard interrupts again immediately after the call.
