Hello all,

Working on the galley (see the latest SVN checkin), I find that 
\box_if_empty:NTF is misleading. The test is for a void box, not an 
empty one:

\box_new:N \l_my_box
\hbox_set:Nn \l_my_box {}
\box_if_empty:NTF \l_my_box { NOPE } { OOPS }

I think it should be \box_if_void:NTF - any objections?
