Maxime Coste 4dac61c864 Fix grep-next/prev-match not jumping correctly to first/last match
When used just after grepping, grep-next-match ended up jumping to
the second match, as `0g` is the same as `g`.

The fix itself is pretty ugly, a better one might be to distinguish
the `0` count from no count given, so that `0g` could fail with
"no such line" or similar.
