* src/chars.c (move_mbleft): Start looking for a multibyte char
not at the start of the string, but only as far back as such a
char can possibly be. Change suggested by Mark Majeres.
* src/search.c (findnextstr): Step backward or forward not simply
one byte but one character (possibly multibyte). Fixes Savannah
bug #42175, reported by myself, and the finding of ghosts seen in
https://lists.gnu.org/archive/html/nano-devel/2015-03/msg00055.html.
