When the commands in the && chain fails after 'cd "$git"' near the top but
not before 'cd "$TRASH_DIRECTORY"' near the end, you would end up starting
the next test from somewhere different from "$TRASH_DIRECTORY".

Do it like this instead:

	"$GITP4" clone --dest="$git" //depot &&
        (
        	cd "$git" &&
                ...
	) &&
        rm -fr "$git"
