Comment 13 for bug 129307

Attached is a new bundle that differs a bit from the previous one in -- I believe -- a better code factorization.

I have started to do so in the attached bundle but I could really use some help for these.

If you are takling about find_format, I did not find any occurrence of
it in bzr-svn.

This is because .bzr/checkout/format is read (which may be redirected too).

BTW,

 bzr co http://users.skynet.be/Pierre.Brukier/anum/projet

also works with the patch.
