Maybe I wasn't clear.  The only purpose of -MF is to override the default
name of the dependencies output file from what it otherwise would have
been.  It doesn't change semantics in any other way; -M and -MD retain
their meanings and behaviour.

If you think the documentation is unclear, a patch would be most welcome.
