Hello,

I have two subversion repositories which I would like to synchronize via
git-svn.  For this, I have set up a git repository and configured two
branches to track the subversion repositories via git-svn:

    mkdir test-sync
    cd    test-sync
    git svn init --stdlayout file://$REPOSDIR/svn-first

    for repos in svn-first svn-second; do
        git config svn-remote.$repos.url      file://$REPOSDIR/$repos
        git config svn-remote.$repos.fetch    trunk:refs/remotes/$repos/trunk
        git config svn-remote.$repos.branches branches/*:refs/remotes/$repos/*
        git config svn-remote.$repos.tags     tags/*:refs/remotes/$repos/tags/*
        git svn fetch -R $repos
        git checkout -b $repos $repos/trunk
    done
    git gc

This gives me two remote and two local branches:

    master                                                                                    
    svn-first                                                                                 
  * svn-second                                                                                
    svn-first/trunk                                                                           
    svn-second/trunk                                                                          

The first step I'd like to do is to "mirror" the manual merges that were
done between the subversion repositories in the past:

    git checkout svn-first
    git merge -s ours --log commit-of-the-first-merge-in-svn-second

    git checkout svn-second
    git merge -s ours --log commit-of-the-first-merge-in-svn-first

This seems to work, but git-gui shows conflicts.  How can I get conflicts
when I use the "-s ours" merge strategy?

```

What do git status and git diff (--stat, --combined) say?

Umm, that's somewhat odd.

Directly after the merge commands, gitk says there are local modifications.
Then I run "git status" which says the working directory is clean.  Then
I re-run gitk, which _now_ shows no local modifications any more.
