I agree that would be ugly. But the current structure, which is:
if (strcmp(arg, "--remotes")) {
handle_refs(...);
cleanup();
} else if(...) {
handle_refs(...);
cleanup();
}
does not seem so bad, and pushes those conditionals into the
handle_refs() function, where they only need to be expressed once (I
didn't look, but I wonder if you could push the cleanup steps in there,
too, or if there is a caller who wants to handle() multiple times before
cleaning up).
