When making changes to different files (i.e. dirty working tree) and committing logically separate changes in groups, often it is necessary to run 'git diff --cached HEAD' to make sure that the changes being committed makes sense. Saying 'git diff --cached' by mistake gives rather uninformative error message from git-diff-files complaining it does not understand --cached flag. Signed-off-by: Junio C Hamano <junkio@cox.net>
