bug#16382: Cut/Copy tool-bar icons issue

[Angelo Graziosi]

Starting

$ emacs -Q &

I notice that when I select some text in the scratch buffer with the 
mouse the tool-bar icons for "cut" and "copy" remain grayed, i.e. not 
active and I cannot cut or copy the selected text clicking those icons, 
but the keys combination, C-w and M-w work as expected.

This occurs with recent trunk with my GTK builds on Cygwin and GNU/Linux 
Kubuntu 12.04.

It occurs also with Windows binaries from 
http://sourceforge.net/projects/emacs-bin (rev. 115804)


Ciao,
 Angelo.
