One way is to use an environment (.ev) to isolate the header processing from
the body of the document. E.g.
.\"______________________________________________
.de H
.\" Any partially collected text is in environment 0.
.\" Push environment 1 onto the stack to avoid interaction with ev 0 .
.\" Note that .lt (length of title) is environment specific.
.ev 1
.tl 'X'Y'Z'
\l'\n(.lu\(rn'
.br
.\" Pop up one environment
.ev
..
.wh 0 H
.br
.sp 10.5i
XXX XXX XXX XXX XXX XXX XXX XXX XXX XXX
XXX XXX XXX XXX XXX XXX XXX XXX XXX Why?
XXX XXX XXX
.\"-----------------------------------------------
See section 17 of the Nroff/Troff User's Manual or .ev in
man troff
