i've tried hg-fastimport/export, the hg-git extension, and hg convert,  
and none of them implement renames.  is this something that is  
inherently difficult to do or just something that is easily  
forgotten?  it's frightening to me to think that every person who has  
converted to hg from git has permanently butchered their history.
