    version.mk: escape values used in VERSION_SED macro
    
    In addition to backslash and ampersand needing to be escaped for
    simple sed RHS strings, we also need to escape comma since we're
    using that as our s/// delimiter.
    
    Pass everything through a macro filter to sanitize it.
