Don't redirect stderr to /dev/null, use -q to suppress the output on stderr.

This one causes an error message to pop up when the last stash entry is dropped:

doener@atjola:git (master) $ echo 123 >> Makefile

doener@atjola:git (master) $ git stash Saved working directory and index state "WIP on master: 2dd6202... Update draft release notes to 1.6.1" HEAD is now at 2dd6202 Update draft release notes to 1.6.1 (To restore them type "git stash apply")

doener@atjola:git (master) $ git stash drop Dropped refs/stash@{0} (e692e43ce03fe0b5f0eb94123123ea61a0f2097a) fatal: Log .git/logs/refs/stash is empty.

git version 1.6.1.rc1.56.g2dd62

After "git stash drop" finished the rev-parse won't complain anymore, even if you recreate an empty .git/logs/refs/stash file, because .git/refs/stash is also gone, and then it doesn't seem to care anymore.

But having a valid ref and an empty log makes it unhappy:

doener@atjola:git (master) $ git rev-parse HEAD > .git/refs/stash doener@atjola:git (master) $ : > .git/logs/refs/stash doener@atjola:git (master) $ git rev-parse -q --verify 'refs/stash@{1}' fatal: Log .git/logs/refs/stash is empty.

Sorry, I missed that 2>/dev/null is used for this purpose there as well.
