For the html output we can use a stylesheet to make sure that the
listingblocks are presented in a monospaced font. For the manpages do
it manually by inserting a ".ft C" before and ".ft" after the block in
question.
In order for these roff commands to get through to the manpage they
have to be element encoded to prevent quoting.
