23c3fd9bcd statusbar: display at most three consecutive alert messages
Cap the number of pauses when displaying ALERT messages, to avoid
making the user wait for ages when tens or hundreds of files were
specified on the command line.

This fixes https://savannah.gnu.org/bugs/?50362.

a847d37b24 tweaks: split the grafting code off from copy_from_buffer()
Later on we're going to need the ability to graft a buffer into the
current file buffer without making a copy of it first.

1cb945fe8e tweaks: rename the functions for moving to and copying from a buffer
The name "filestruct" was a mistake.  What was meant was:
buffer -- a linked list of structs that each describe a line.

61e8b3d542 screen: don't hide two-column characters at left edge in softwrap mode
When in softwrap mode, no "$" continuation characters are displayed,
so the code that reserves space for them should be skipped then.

a8c1dc1402 rcfile: don't accept empty regexes for syntax coloring
As a small service to the user, reject empty regex strings,
because an entirely empty regex simply doesn't make sense.

d60e7d374c spelling: correctly adjust the length of a single-line region
When the marked region covers only a single line (or a part of it),
its new endpoint is not simply the length of the last line of the
spell-checked text, but instead the old endpoint plus the /change/
in length.

c24545fe9a tweaks: always directly do a refresh when the margin changes
The previous code only directly refreshed the screen when the margin
changed due to toggling line numbering on.  When the margin changed
due to toggling it off, it would indirectly refresh via do_toggle().

9ec546d293 tweaks: rename a function, and drop an unneeded parameter
When replacements are made, nothing needs to be reset any more
(it was done insufficiently anyway).  Just make sure the screen
is refreshed when all is done -- this may be superfluous when
doing interactive replacements, but not when replacing all.

b3bcc8eeac painting: make use of the multidata of the preceding line
When painting a line, the multidata of the line /before/ it is valid
in most cases: it was determined just a moment ago.  And it tells us
all we need to know: whether there is an unpaired start match before
the current line or not.

The only exception is when painting the first line of the screen:
the multidata of the line before it might be stale.  So for the
first screen line we will always have to do some backtracking.
But that is left for later.

914af36546 spelling: don't unnecessarily fiddle with the viewport
If we're somewhere deep into the file and do a spell check, and the
first misspelled word happens to be right there, onscreen already,
then this word does not need to be centered -- it /should/ not be
centered.  We should scroll only when necessary.

8f10e364bb replacing: stop searching in a region when edge of buffer is reached

doing replacements in a region, because a region cannot straddle the
buffer's edges.

94e563232e general: stop the spell checker from crashing after the changes in search
The spell fixer does not provide a beginning line, so the search routine
should then not try to refer to any data of this line.  Also, since the
changes to the search routine there is no need any more to retreat one
step before starting to search for a misspelled word.

ef7a7c5360 replacing: ignore the first match when the user said no
When the user answered No to a replacement prompt, skip the match
at the current position, so we don't stay stuck there.

Also, when replacing in the backward direction, or the match is
of length zero, skip the match at the current position, to not
get stuck.

64aa8757a8 search: make the \b and \B anchors work correctly in both directions
That is: remove the special treatment of BOW anchors, and instead make
regexes match against the whole line instead of against an artificially
shortened one, because the latter method creates ghost matches: matches
at the starting point of the search that aren't really matches when seen
in the context of the whole line.

3534d8ff25 replacing: compensate cursor position only for replacements /before/ it
When a replacement happens right at where the cursor sits, the position
of the cursor should not be adjusted, because the real cursor position
is between the current character and the preceding one: the place where
the cursor is shown is in fact right /after/ the insertion point.
