[PATCH] git stash: Give friendlier error when there is nothing to apply

[Ori Avtalion <ori@avtalion.name>]

The old message was scary and included a 'fatal' error from rev-parse:
     fatal: Needed a single revision
     : no valid stashed state found

The new message is identical to the one given by 'git stash branch', and
given *before* the check for a dirty working tree.

Previously, the command prompted the user to clean a dirty working tree
when there is nothing to apply.
