If I understand correctly, this is a documentation bug and feature
request.

The documentation bug: the "git diff" documentation says something
like

	git diff [--options] [<tree>[..<tree>]] [--] [<path>...]

but the <path>s after "--" are actually patterns (path specifiers).
See [1] ([RFD] git glossary: define pathspec, 2010-11-29).

The feature request: there is no way to specify an "exact match"
or "negative match" when specifying paths.  At least "negative
match" has been suggested before.
