Yes. On that. It would be nice if git-svn could also fake setting remote merge properties, too.

Some beginnings at:

  http://git.catalyst.net.nz/gw?p=git.git;a=shortlog;h=svk-merge
  (pull from git://git.catalyst.net.nz/git.git#svk-merge)

What it needs to do;

  0. preserve the notion that commits tagged with "git-svn-id:" should
     not vary depending on who synced them.

  1. on commit, if we're committing a merge, make sure that the other
     parent has the same revision somewhere in the repo, and then set
     the "svk:merge" and "svnmerge-integrated" tags to accurately record
     which parent SVN revisions are used

  2. when fetching revisions, spot these tickets and set parents
     appropriately.  In the case of SVK, the merge tickets may
     correspond to revisions in (inaccessible) svk local depots.  It may
     be possible to infer these extra parents in some limited
     situations using the extra information svk puts in commit messages
     by default, but I doubt that is a useful endeavour!

I'll take a look at what you've been working on and see if that's not what you're already trying...

Sam.
