Plugins.  (This would also be the case for the revision-number 
finding code.)  We could just add a "setuptools.vcs_filters" entry 
point group wherein filter functions could be registered.  Most VCS 
support is through plugins anyhow, so it's no big deal for them to 
define a function and add another entry point.
