I see that there are existing "int i" for counting worktrees in
worktree.c, FWIW for new code I wouldn't mind if it's "size_t i"
instead, to make it future proof (and to eventually get rid of cast
warnings as we move more things from "int" to "size_t").

You added this function in the last commit, let's just skip adding the
braces to begin with, rather than this style-fix after the fact.
