Importing merges when converting repos from SVN to Git (fusing grafts in the Git history)

Hi list, I'm in the processing of converting the SVN repos of my company to Git. We have been using scripts to handle the merge hell with SVN and these scripts always mentioned what was merged where in the commit message. The first line is typically: merge -r FROM:TO https://svn.fake-company.com/svn/project/{trunk,branches/branch-name} I'm going to import the repositories with `git-svn' and then I'd like to rewrite the entire history to take these merges in account in the Git repo, if possible. This will probably help us merging the (former) SVN branches in our new Git repo. I know I can simulate a merge with a graft and I think it will be fairly easy to write a small script that parses the log and generates the corresponding graft file. Now the question is: how to make these grafts part of the *real* history so that we don't have to depend on the graft file anymore?

I know this issue has already been raised on the ML (the "how to include grafts are real merges in the history" thing) but I couldn't find the corresponding posts and can't remember the conclusion...

Thanks!
