bug#23629: 25.0.94; Calc: Yanking with mouse-2 does not use X primary selection/clipboard

[Bastian Beischer <bastian.beischer@rwth-aachen.de>]

This patch solves the issue for me.

I don't know how the duplicated documentation is supposed to be
handled. If the documentation is put on the internal function it's
less likely to be seen, but if it is put on the two disjunct functions
it's duplicated. What's the preferred way?
