Or because ce cannot be NULL? If it's the former, I think it's clearer if we check that ce is not NULL either way.
It is NULL if one tree misses an entry (e.g. a new or removed file). free handles NULL and we generally avoid duplicating its NULL-check.
You're probably referring to the non-merge case as the example for checking. That one is different, though, because there we call do_add_entry instead of free, which does not handle NULL. And it doesn't have to, as it is mostly called through add_entry, which never passes NULL.
