It depends on what you are trying to do. An obvious thing to do is to
accept the fact that it has always been a regexp match, and quotemeta your
input string.
Because we allow you to give "-F" and "--author=foo" in any order, looking
at the options we have seen already and adjusting the pattern depending on
the fixed-string option in the code would not be workable. You would have
to instead queue up all the --grep/--author/--committer options until the
very end and _then_ compile them at the end, after you saw all the other
grep related options such as -i/-F/-E
I am not interested in helping people with attitude very much ;-), but one
somewhat related thing I have been wanting to add was the change in the
attached patch. It allows you to anchor not just at the beginning but at
the end.
