Doesn't meet my observations.

In the original case cursor motion followed an exchange-point-and-mark 
over a string found.
Afterwards, moving the cursor, any active region went into the 
clipboard. Next yank got it from there.
Whilst the string found and copied has been expected, but was not returned.

Ie got some arbitrary content resp. to the move away from the match-point.

The big difference IMHO is the cursor-motion-region-setting in emacs.
In X, regions are expressingly marked, while in Emacs it just the 
difference beween point and any previously set mark.

Therefor it not that clear, if an existing region has an editory meaning 
as in X, it might just happen.

For me the matter is done setting `select-active-regions' not t.
I'll expect others with difficulties here.
Maybe lets postpone the issue.
Should no one else reports trouble, fine.

Thanks all BTW. Great joy always and again with Emacs.
