Thanks.

Hmm, I don't understand, could you elaborate/rephrase?

"foo >=" without a version doesn't make sense to me, for example rpmbuild 
doesn't let "Requires: foo >=" pass.  Is it actually possible to have such 
relations that have name, the = >= and friends bits, but no version in 
packages?

In the commit message where the patch was reverted, it says "This isn't right 
... Eg. =>, (None, None, None) VS. < (1, 2, 3) is false.".  Isn't 
formatRequire() just for formatting stuff for humans to read, what does it 
have to do with actual version comparisons?
