Thanks for the detailed report, I think the problem is that when rebase 
stops for the user to resolve conflicts it writes .git/MERGE_MSG which 
is removed when the conflict resolution is committed or by 'git reset' 
if the user skips the commit. In this case the commit is effectively 
skipped but the file is not removed and so seeds the editor when you 
next make a commit. I'll try and put a patch together next week.

Best Wishes
