No, this may be better. Add a flag to say "returns linked worktrees
_only_". Which means when you're in a "normal" repo, get_worktrees()
with this flag returns NULL. When you're in a multiple-worktree repo,
it returns all linked worktrees (no main worktree). I think I might
have a use for this flag in addition to this uses_worktrees() here.
uses_worktrees() look quite simple with that flag
int uses_worktrees(void)
{
struct worktree **worktrees = get_worktrees(WT_LINKED_ONLY);
int retval = worktrees != NULL;
free_worktrees(worktrees);
return retval;
}
