revision: avoid leak when preparing bloom filter for "/"
If we're given an empty pathspec, we refuse to set up bloom filters, as described in f3c2a36810 (revision: empty pathspecs should not use Bloom filters, 2020-07-01). But before the empty string check, we drop any trailing slash by allocating a new string without it. So a pathspec consisting only of "/" will allocate that string, but then still cause us to bail, leaking the new string. Let's make sure to free it.
