Re: format-patch on permission change gives empty patch

When I ask git to format-patch a commit that is just a file
permission change, it ends up generating an empty file, not
even the commit message is included.

Ok it turns out that the commit in question was a NOP since the file
permissions didn't change.

But even if the patch is truly empty, format-patch should still give
me the commit message shouldn't it?
