Subject: [9front] [PATCH] troff: we are not htmlroff
Reply-To: 9front@9front.org
Precedence: bulk


If we don’t explicitly check for ‘h’ in troff, we can’t reliably check
for non-htmlroff well.

Consider the following:

	.if h \{\
	.	de M
	.		tm m
	..\}

Without this change, this will print m and not define macro M.
