Well no (but I tried now, see below). The reason why I did not:

    + the repo is already pushed and shared since a couple of years

    + the vast mayority of changes (400 changesets) were only done in bibgraf.bib. So converting might not really reduce the number of changesets

Well I did what I always did (in a sandbox)

    + hg clone /home/user/HGs/tex/bib/ bib-clone

    + filemap contains
      include bibgraf.bib

    + cp filemap bib-clone/

    + g convert --datesort /home/oub/tmp4/bib-clone/ /home/oub/tmp4/bib-repo --filemap /home/oub/tmp4/bib-clone/filemap  

Then bib-repo has 363 instead of 406 changesets.
And in addition I have to delete my helix repository and create a new
one. The problem is that this will confuse my collaborators who have no
idea about mercurial at all, save push, fetch (not pull+merge), commit
and clone.

But if I push that now my collaborators pull hg log -G might confuse them

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


Now results also in

As nifty as the idea sounds, I am not sure I can use it, thanks
