New description:

 The SFTP frontend currently allows deleting a non-empty directory. This is
 a well-defined and useful operation on a Tahoe filesystem, but it would
 not be allowed on a POSIX filesystem.

 It's unclear whether applications using SFTP via sshfs might rely on
 attempts to delete a non-empty directory being denied. In principle they
 could, but I've no evidence that this is common.

 TODO: check whether {{{rm [-r] [-f]}}} on platforms that support sshfs
 explicitly checks that a directory is empty before trying to delete it.
