Do you remember what you did to get the repo in this state?  I've never
had this issue before (though I generally update with -C to get a clean
slate).


According to the code, it appears the filesystem contains these:

  .hglf/doc/04.MSC-Mill Level 2/04.07.Training/04.07.01.PCFC Training.ppt
  .hglf/doc/04.MSC-Mill Level 2/04.07.Training/04.07.01.PCFC Training.ppt.orig

which makes it want to try to copy this:

  doc/04.MSC-Mill Level 2/04.07.Training/04.07.01.PCFC Training.ppt

to this:
 
  doc/04.MSC-Mill Level 2/04.07.Training/04.07.01.PCFC Training.ppt.orig


But the source ppt file doesn't exist.  It seems like a bad assumption
that if the standin file (under .hglf/) exists, the actual largefile must
exist.

Moving this repo somewhere else and recloning should fix this if you are
in a pinch (and I suspect so would 'update -C' or deleting the *.orig
files and updating again), but I'm interested in getting more info about
this before this particular state gets destroyed.
