Re: highlight with mouse then shouldn't need kill-ring-save?

[Richard Stallman]

       Perhaps it would be good in transient mark mode
       to set things up so that when the mark is active,
       the region is available as a selection.

    The problem here is that if you use transient-mark-mode (I do) then
    you activate the region often, for a variety of reasons, mostly
    unrelated to the kill ring.  So if each time the active region got
    copied to the kill ring, then the kill ring could easily get clobbered
    with unwanted entries.

We certainly wouldn't want it to be in the kill ring.  But Emacs could
make it available as the selection to other X clients, without putting
it in the kill ring.

Currently Emacs' selection is always from the kill ring, but that does
not HAVE to be so.  Maybe in Transient Mark mode the selection should
be defined as the highlighted region (when and if there is one).
