This looks good to me. I've checked that refname_match (and
branch_merge_matches(), which returns the result of refname_match()
directly) is only used in "if" contexts, so making it return a value
other than 1 is fine.
I would initialize best_score to INT_MAX to avoid needing the
"best_score < 0" comparison, but don't feel strongly about it.
