Thanks for applying the changes, and argh, in turn, please forgive me!
I don't like the strange gmail web interface (particularly when
applied to a high-traffic lists...l), only just found your reply  :-(

Essentially, but see *** about setting of the primary selection.

*** Well, indeed.   In part  3 of the hack, where I used
activate-mark-hook (used in transient-mark-mode),  by the description
of activate-mark-hook, I was expecting activate-mark-hook to be called
and therefore primary to be set whenever the mouse IOR the keyboard
was used to set or adjust the active region and transient-mark-mode
was on, but it doesn't seem to quite work as intended (not sure as yet
whether that's my fault or a bug, should investigate further I guess).
 If it were working as I expected, it would reflect the behaviour of
other recent X11 applications, where using the keyboard to highlight
sets primary just like using the mouse does.

I realise you're probably not using transient-mark-mode, though.  But
if x-select-enable-primary is non-nil, then x-select-text*  propagates
back out to primary, so you can still affect primary from the keyboard
if you want, just use different settings.   Even more flexibility (and
potential for confusion...) might be to have 4 (6? - secondary :-)
separate  x-select-enable-[primary|clipboard]-for-[cut|paste]
settings, in case people want things squirted out to primary but not
sucked in from it and so on.
