^^^ Strictly that's not true, it also replaces kills made by mouse-drag 
i.e. an already active region (otherwise you would drag select a region 
with mouse-1, then mouse-3 extend, and you'd get two kill ring entries).

Here's one with revised doc phrasing.

...I haven't tried making shift-selection respect 
"mouse"-"drag"-copy-region as yet, but that should be straightforward 
given similarity to the "select-active-regions => 'only" code path. 
(It's not like I'm personally going to use mouse-drag-copy-region => t 
in any case....)

The customization name would then be kind of misleading, but, well, it 
has company.   Effectively, mouse-drag-copy-region would "really" be 
something like the (hypothetical) "clipboard-active-regions => 'only" in 
end effect, though probably implemented by hitting the kill ring and 
thus (maybe) the os clipboard as a side effect, so maybe
"killring-active-regions => 'only" would be more accurate.
