Subject: better mangling test. We now test that we can create by long name and
 delete by short name, and that we can create by short name and delete by long
 name

our old mangling code fails this test.

also tweaked the random filename generation to produce more likely
collisions
(This used to be commit 65609c52960c2b5938150a2fdb5290541f4e0225)
