Hello, I'm using Git 2.13.1 (from the Debian sid repository) and noticed the following issue when upgrading. $ git diff --compaction-heuristic error: invalid option: --compaction-heuristic $ git diff --cached --compaction-heuristic usage: git diff [<options>] [<commit> [<commit>]] [--] [<path>...] I know that --compaction-heuristic is no longer supported but I was using it an alias and was confused that I got no proper error message warning me which option was wrong. It seems to happen for any invalid option which is used in combination with --cached or --staged.
