From d6cc2df5c80dc4f52a56679baa5e32539eb028b1 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 20 May 2015 14:01:32 -0400 Subject: stash: complain about unknown flags The option parser for git-stash stuffs unknown flags into the $FLAGS variable, where they can be accessed by the individual commands. However, most commands do not even look at these extra flags, leading to unexpected results like this: $ git stash drop --help Dropped refs/stash@{0} (e6cf6d80faf92bb7828f7b60c47fc61c03bd30a1) We should notice the extra flags and bail. Rather than annotate each command to reject a non-empty $FLAGS variable, we can notice that "stash show" is the only command that actually _wants_ arbitrary flags. So we switch the default mode to reject unknown flags, and let stash_show() opt into the feature.
