(branch-creation time) up to 43067. 43068 and 43069 contain a little swapping action between re.py and sre.py, and this mightily confuses svn merge, so later changes are going in separately. This merge should break no additional tests. The last-merged revision is going in a 'last_merge' property on '.' (the branch directory.) Arbitrarily chosen, really; if there's a BCP for this, I couldn't find it, but we can easily change it afterwards ;)
