[PATCH] ls-tree: handle trailing slashes in the pathspec properly.

This fixes the problem with ls-tree which failed to show
"drivers/char" directory when the user asked for "drivers/char/"
from the command line.  At the same time, if "drivers/char" were
a non directory, "drivers/char/" would not show it.  This is
consistent with the way diffcore-pathspec has been recently
fixed.

This adds back the diffcore-pathspec test,dropped when my
earlier diffcore-pathspec fix was rejected.
