Something like this?  Just kidding...


 SYNOPSIS
 --------
+[verse]
 'git diff' [<common diff options>] <commit>{0,2} [--] [<path>...]
+'git diff' [<common diff options>] <tree-ish> <tree-ish> [--] [<path>...]
+'git diff' [<common diff options>] <blob-or-path> <blob-or-path>

Possibly that <tree-ish> can be also a <directory> (on filesystem).

You can e.g. use

  git diff HEAD:git-gui/ 00e9de7^^
           ^^^^^^^^^^^^^ ~~~~~~~~~
           \-- tree       \-- commit (in subtree-merged history)
