Thanks for the information. After unpulling, etc, what's the best way  
to record those changes as a patch that I can apply to the master  
repository? (After all, the goal is still to get a file in the master  
repository to look like an arbitrary past version.)

If I recall correctly, a basic unpull operation isn't something  
that's recorded as a patch -- and so couldn't be 'recorded' and  
'pushed' to the master repository. In addition, if I unpull in a temp  
repository and then modify some file and record that patch, will that  
patch apply cleanly to the master repository, where the context is  
different?

Thanks,

Zach
