I've been lurking on this thread, collecting the valuable feedback.  Thanks
all.

I just want to clarify one point about darcs1 vs. darcs2.  The darcs2
program works on both darcs1 and darcs2 format repositories.  When it works
with darcs1 format repositories it works the way darcs has always worked on
darcs1 repositiories.  Thus, it's not fair to say that the above problem
exists in darcs2 format repositories since the GHC repository was never
publicly converted to darcs2 format.  So, the spinning of the darcs2 program
on the GHC repository is due to flaws in darcs1 format that have hopefully
all been corrected in darcs2 format.

Yes, this is a known bug, but also one that has received considerable
effort, and is currently presumed to be fixed for darcs2 format
repositories.  Bug reports and test cases to the contrary are welcome.
