I realized that, in conjunction with Joel's changes to the NEWS file,
this push now says that gdb-8.3 no longer supports Python versions
less than 2.6.  This is technically true due to the commit of the
two argument version of gdb.Value that I pushed yesterday.
(That commit uses the PEP 3118 buffer protocol which is only
supported in Python versions 2.6 and up.)

So...

I've pushed this documentation commit to gdb-8.3-branch also.

I won't push "Use Python 2.[67] / 3.X / PEP 3118 buffer protocol"
to the gdb-8.3-branch unless someone asks for it though.
