Revert "Create first merge point for Git"

This reverts commit 907260eea3c3b1833f70d7a33b34739a81e0eef4, reversing
changes made to f45977684ae3997e212a9f0ea36ea6677be47867.

The reverted commit undid a number of previous (i.e. svn) merges from trunk to branches/release. I don't know why it went wrong, although it may have been operator error on my part.
