[yt-dev] Milliparsecs

Well, count me as a not terribly passionate -1. I think the idea that
coding around the habits of certain subsets of users of yt has gotten us
into trouble in the past, and I'm wary of doing it here. While this is
certainly not a huge deal, I personally prefer that we be stricter about
units standards. However, I totally understand that milliparsecs is not
used by anyone. And of course, parsecs are not SI to begin with, so I
suppose from a PURELY logical standpoint, we aren't necessarily bound by
their prefix conventions.
