Subject: Render the man pages that generators write

DocBook, pod2man and hand written pages leaked roff onto the page: font
escapes inside no fill blocks, comments, layout escapes such as \% and
\c, the colours and half line moves around DocBook's links, and the
requests and macro definitions their preambles open with. Those now
draw nothing, the common named characters and strings render, .EX and
pod2man's .Vb read as code, a .TP tag takes a line of its own and the
alternating font macros switch fonts between their arguments. Anything
rarer still falls back to its text.
