BUG: "git stash apply <arg>" broken, "git-stash apply <arg>" works

Synopsis: "git stash apply stash@{1}" doesn't work, but "git-stash apply stash@{1}" does.

Platform: win xp (yeah, I know, I know) msys (Git-1.5.5-preview20080413.exe) git version 1.5.5.1015.g9d258

To reproduce:
	# Create a minimal repo
	mkdir stash-bug
	cd stash-bug
	git init
	echo line1 > file
	git add file
	git commit -m initial

	# Create the stash that we'll use
	echo "This is correct" > file
	git stash save "Save off correct line in what will be stash@{1}"

	# Create another stash (the default one) which we won't use
	echo "This should not be shown" > file
	git stash save "Save off incorrect line in what will be stash@{0}"

	# They are correctly created
	git stash list

	# "git-stash apply arg" works
	git reset --hard
	git-stash apply stash@{1}
	echo "git-stash apply respects its argument"
	cat file

	# But "git stash apply arg" doesn't
	git reset --hard
	git stash apply stash@{1}
	echo "git stash apply (no dash) doesn't respect its argument"
	cat file
