The patch below (against the current CVS trunk) makes focus return to
the frame regardless of the value of x-gtk-whole-detached-tool-bar
(i.e., it works both with the proxy (arrow) and the whole detached tool
bar).  Jan D. or somebody else who's familiar with GTK+ should check to
make sure it does not cause any problems elsewhere.

	* gtkutil.c (xg_tool_bar_callback): Return focus to the frame
	after we have clicked on a detached tool bar button (bug#1405).
	This replaces the reverted change below.
	(xg_tool_bar_proxy_callback): Revert previous change (bug#1405).
