bsdtar's mtree format has a quirk wherein entries without "/" in their first word are treated as "relative" entries, and "relative" directories will cause tar to "change directory" into the declared directory entry. If such a directory is followed by a "relative" entry, then the file will be created within the directory, instead of at top-level as expected. To mitigate, we append a slash to top-level directory entries.
Fixes #851.
