how should we proceed with the libgo part of this patch?  I can checkin
the rest (which contains functional changes) now and omit the libgo
part (either for now or completely, given that it consists only of
comment changes).

What's the procedure for libgo here?  IIUC, only the trunk version of
libgo is imported from upstream, while changes to branches can go in
directly.
