I think I understand that.. I can't "remove" the existing history (by
replacing the repo with my other one) because the history is being used by
tags. And hence the option you are proposing is to merge the two repos
together and hiding away the SVN imported one. Which seems like a
reasonable option for Predef since it doesn't have a long git history (but
slightly longer and more detailed than the svn history).

I must confess I don't understand the git commands.. But I do understand
your comments of them. Am I to assume you've mostly tried them? I ask
because I'm ok blindly following them once. But will likely fall flat on my
face if something goes wrong :-)
