Any match is returned by setting @match_start to the first character
of the match and @match_end to the first character after the match.
The search will not continue past @limit. Note that a search is a
linear or O(n) operation, so you may wish to use @limit to avoid
locking up your UI on large buffers.
@match_start will never be set to a GtkTextIter located before @iter,
even if there is a possible @match_end after or at @iter.
Searches forward for @str.
