Not in setuptools 0.6 it isn't.  However, it's really only useful for
*adding* files not picked up by revision control; it can't *remove*
files found by revision control.

Manifest and revision control support are semi-independent, as it's
quite possible to have files you don't put in revision control but
which nonetheless need to be included in an sdist.  (For example, you
might want to have Cython/Pyrex-generated C code, or compiled
documentation files.)
