What do you think about making that xrev part of the pkgrel? Instead of
0.7_1-2 you'd have 0.7-1.2 < 0.7.0.1-0.1. And even if haskell-core
continues using that underscore, 0.7-1.2 < 0.7.0.1_0-1.

It's not very common to have a decimal Pkgrel, and I'm not sure if it is
good practice, but I've used it, in fact for Haskell packages in
particular.
