If match n°2 is not inside a string, I think we should not skip all
that's matched by the regexp (since it's not a string and may hence
contain other things that need to be syntax-propertized). I.e. The
`unless' should be turned into an `if' and in the non-string case it
should move point back to (match-end 2).

`syntax-ppss' moves point, so that's taken care of. See the second test
in the same commit.
I agree that that's not obvious from reading the code, though.
