I have applied these patches, and in fact I have applied them to 'master' because that if where I think they belong. Eventually 3.2.2 will be whatever is on 'master' at that time. I might create a devel-3.3 at some stage to do some brand new development, but these patches are just a continuation of what went into 3.2 and 3.2.1 so I think this is where they belong.
