Perhaps I wasn't clear -- I didn't mean that the synopsis *only* listed
the form in my original quote above.

I simply meant that

   git checkout [-p|--patch] [<tree-ish>] [--] [<paths>...]
   git checkout [-p|--patch] [<tree-ish>] [--] <pathspec>...

aren't identical even though I assume they describe the exact same
scenario. The first command synopsis makes it clear that paths are
optional while the second indicates that at least one path must be
specified (unless "..." means "zero, one, or more occurences").
Also, "paths" != "pathspec".

Sure, but it won't be during the coming week. Not that the patch is
terribly difficult to prepare but because I need legal approval to
submit it, and it's not clear I'll have time to deal with all that
during my last week at work.
