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.
