Reported-by: Peter Passchier <email address hidden>
Reported-by: Liu Hao <lh_mouse@126.com>

Bug existed since version 5.6, since a special color for highlighting
search matches was introduced in commit 87fe73dd.

feedback: make Full Justify show a message also when using --minibar

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.

painting: trigger a refresh when a second start match appears on a line

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.

painting: trigger fewer unneeded full-screen refreshes

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.
