Dhiru, Lukas,

I'm implementing support for $ml$ format with '.' delimiter. From what I can google, a grub hash looks like this:

grub.pbkdf2.sha512.10000.4483972AD2C52E1F590B3E2260795FDA9CA0B07B96FF492814CA9775F08C4B59CD1707F10B269E09B61B1E2D11729BCA8D62B7827B25B093EC58C4C1EAC23137.DF4FCB5DD91340D6D31E33423E4210AD47C7A4DF9FA16F401663BF288C20BF973530866178FE6D134256E4DBEFBD984B652332EED3ACAED834FEA7B73CAE851D

So what format *do* we support? Why do we use a '$' delimiter? Can I drop that?
