How can a pathname have more than one trailing slash? Either you have a
trailing slash to imply you are referring to a directory *only* or none to
imply that it can be a filename [or a pathname].

The implementations I know of -equate foo/ with foo and vice-versa.

where else besides at the end of the pathname? that is the only location
that matters.

If I understand correctly, both of these should succeed and do an mkdir
xxx
