[Haskell-cafe] I think we should stop "fixing" other people's packages on Hackage silently

People expect the version number to uniquely identify the version of the 
package, so I think the Hackage revision should be included in the 
version number.
If that means ugly version numbers: So be it, it's an incentive to tell 
upstream to update their code :-)
