Occasionally when you do a simple search (F7) in mc's built-in viewer
while viewing a manual page, it doesn't find some yellow or red (bold or
underlined) text.
Patch attached to fix the problem.
Example test case: See the attached file that contains abababc in bold
(that is, each letter followed by a backspace, then the same letter
again). Search for ababc and it won't match that string, though it
should.
Explanation (line numbers according to 4.6.2):
In src/util.c: _icase_search() line 812-815 you increase e (the haystack
pointer) and dlng (counitng characters that were skipped because of a
backspace) every time you skip a character and the subsequent backspace in
the haystack. Later, in line 819, if the partial match turns out not to be
a complete one, you rewind the haystack pointer by the number of chars
matched from the needle (d - text). This, however, forgets about the
forward steps that were taken in haystack because of the backspaces. So
next time the substring match starts from the wrong position.
