I've done some more digging and am still rather confused. I'm fairly sure 
that the patch cache can have compressed files, and it seems that 
inventories might be compressed too. What about pristine?

I also discovered that darcs optimize --compress ought to do much of 
what's needed to do the fixing, but that http://bugs.darcs.net/issue1248 
is a bit of a showstopper in that regard. I've bumped up its priority to 
'urgent' on that basis and the general fact that it is a (local) repo 
corruption bug.
