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? -- Joseph Wright
