Uh, I think there's some confusion here. David, you need to make a  
copy of the repo and use unpull. Unrecord is the exact opposite of  
record -- it forgets the patch you just made, but does not alter your  
working directory. I can't think of any situations where unpull would  
fail but unrecord succeed.

You can get the diffs, so something like this may work (albeit  
awkwardly):

darcs diff -u --from-patch="Some patch" file-to-diff.c | patch -R -p1

You can then revert it back to your current copy. (Be sure to back it  
up if it had un-recorded changes.)
