Implements a none match for git log, which is useful from time to
time to e.g. filter FIXUP message out of git log.
Internally, the bol 'all_match' was changed to an int 'all_or_none'
taken the values 0, GREP_ALL_MATCH or GREP_NONE_MATCH.
For git grep a similar functionality can achieved by the existing
--files-without-match option.
