Bug#901249: xterm: translation overrides for copy/paste do not work as documented

[Ondřej Kuzník <ondra@mistotebe.net>]

I've had the following in my .Xprofile for a few years:
XTerm*VT100.translations: #override <Btn1Up>: select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0)

Since the last upload, mouse selection has become highly unreliable and
it takes three selection attempts to actually get something into the
clipboard. On the first try it just seems to deselect immediately, the
second time text stays inverted, just sometimes never makes it into the
clipboard and sometimes an old selection makes it back into the
clipboard even when I've been able to paste the new one just before,
which is even more confusing.

Is this a bug with the new version or do I need to update the
translations to copy the selection so that it can be reliably used both
in middle clicks *and* Shift-Insert pastes?

Thanks,
Ondřej
