So my problem appears to be not with bad renames, but with bad 
merges (caused by deficiencies in the SVN->Hg conversion I've 
pointed previously) involving renamed files - the renames are not 
accounted for in the merged revision.  Could the 'fixrenames' 
extension also handle re-merge with similarity detection of such 
merge revisions?
