That makes a lot of sense.  The rename must have been a side-effect of pulling 
the project out of a BerkeleyDB repository with a bunch of other projects into 
its own FSFS repository.  Revisions 1120-1123 are all similar.

Well, I can't expect 'hg convert' to deal with an edge case like this.  It 
would appear that my only options are to either baseline the HG repository off 
r1124, or stick with SVN for the moment.

Thanks for looking into this.
