"Stash save" exits with 0 when nothing to stash

Hi,

When calling "git stash save" in a clean situation (no change since last
commit), git-stash reports "No local changes to save", which is OK.
But it exits with code 0, despite no stash has been saved.
It would be better to exit with code 1 in this case.

N.B. In a similar situation  "git commit -a -m 'Test'" reports

On branch master
nothing to commit, working directory clean

and exits with code 1.

Thanks
