Well this complicates things a bit and also defies the idea of VC

This is also quite large.

I came up with the following «bright» idea

In the bibtex repo:
 hg up 0
 hg branch bibtex
 hg revert bibtex -r 409 (which is tip)
 hg commit -m "Start the bibtex branch"

Then in the latex repository I run

 hg pull /home/user/bib -b bibtex --force

But then in my latex repository I see 
hg log -G

That looks also odd.
