Hmm, I just tried it and it looks like the default SF produced by this 
function doesn't have any overlap. So that won't work for me.

Guess I might need a Fortran interface for 
PetscSFSetGraph/PetscSFGetGraph after all. If you could put one it that 
would be great.

Another simpler possibility that would work for my case is if there was 
a DMCopySF() function for copying the point SF from one DM to another. 
Up to you if you think that would be of enough general usefulness to 
warrant inclusion.
