I don't believe that will work; 3239677 (current master) already has
develop recorded as being present, so you get:

  llc[431]$ git merge --no-ff develop
  Already up-to-date.

without any change.  Since git-merge does not have a "-s theirs"
parameter, the following does work:

 git checkout -b hack develop
 git merge master -s ours \
    -m 'Merge to sync develop and master preferring develop'
 git checkout master
 git merge hack
 git branch -d hack
 git checkout develop
 git merge master

That last two merges are fast-forward, which is fine in this case.
Check the results before you push (in fact, check the results after each
step so you understand what it's doing).
