 $ # show test succeeds
 $ mkdir -p foo/bar/baz
 $ find ./foo -delete
 find: -delete: ./foo: relative path potentially not safe
 
 The reason that fts_accpath contains a leading ``./'' in this case is
 that fts, even without FTS_NOCHDIR, does not chdir into the parent
 directory of depth 0 directories on the first pass, fts_accpath will
 always equal fts_pathname on depth 0 FTSENTs.
