This is a bit more mundane than recent discussions, but I noticed that the ms macros contain this
.ie h .ll \\n(LLu
.el \{\
.ll 5.0i
.if n .if \\n(TN .ll 29
.if t .if \\n(TN .ll 3.5i \}
as part of .de TL. What is '.ie h'? I thought the only single character
conditions were e, o, n, or t. /sys/doc/troff confirms this, and a look
at the sources left me wondering. So, again, what does '.ie h' mean?
Thanks.
