-The \-width argument to

-the fact).
-.\" LIST-ITEM
-.It
Some character sequences in groff are not handled depending on escape
style, e.g.,
.Sq \e(ba
.Sq \e\e ,
it will obviously not render the subsequent sequence. Even newer
versions of groff seem to dither on this.
+.\" LIST-ITEM

+In groff, the
+.Sq \&.Fo
+macro only produces the first parameter. This is no longer the case.
