[darcs-users] Duplication between Prim and Commute

[Trent W. Buck]

Whoa, déjà vu.  Did I already report this?

Currently Darcs.Patch.Prim and Darcs.Patch.Commute contain huge swathes
of documentation that's identical.  Also, the following are defined
identically in both files:

    data Perhaps
    toMaybe
    toPerhaps
    clever_commute
    speedy_commute
    eq_FL (this one is near the bottom, and hard to spot!)

And this is defined *differently* between the two files!

    everything_else_commute

Can someone who understands these innards work out which version to keep
and send a patch to turn the other half into module imports?
