Ok, now we're on darcs-devel so we can talk code.  I suppose a sensible 
design would be to have each command return a list of string pairs 
representing additions to the posthook environment.  For the moment, 
they would all return [] except for apply, which would return something 
like [("darcs_patch_count", "7")].  Let me know if there's another 
approach you'd prefer.

I see run_posthook in Test.lhs, which looks like the place to begin, and 
there's also consider_running in DarcsCommands.lhs.  Hopefully the type 
checker will make it clear how to proceed from that point.  Guess it's 
time to deal with the frustration of being an "expert beginner" all over 
again...

Any hints are appreciated, but please CC me.

Cheers,
