[PATCH 0/3] stop storing trailing slash in dir-hash

This series alters name-hash so that it no longer stores the (redundant)
trailing slash with index_state.dir_hash entries. As an intentional
side-effect, the series fixes [1] in a cleaner way (suggested by Junio
[2]) than either [3] (680be044 in master) or [4].

As noted by Peff [5], this change is at a fairly fundamental level, so
care has been taken to ensure that all tests still pass (thus it at
least does not break anything covered by the tests).
