[PATCH] stash show: use default pretty format

[Tay Ray Chuan <rctay89@gmail.com>]

By default (ie. when stash show is invoked without any arguments), the
diff stat of the stashed changes is displayed. Let git-diff decide the
default pretty format to use.

This gives git more consistency, as users who have set their
pretty.format config would naturally expect `git-stash show` to display
the diff in the same pretty format as the other diff-producing procelain
like git-log and git-show.
