Since the C/A/T held only four fonts, there was no room for
Courier. But when we moved beyond that typesetter, inertia
kept the old ways . Finally, in v9, I introduced the fixed-width
"literal font", L, in -man and said goodbye to boldface in
synopses. By then, though, Research Unix  was merely a
local branch of the Unix evolutionary tree, so the literal-font
gene never spread.
