[PATCH] Force listingblocks to be monospaced in manpages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

How about this?

Seems to work for me - but I'm not an asciidoc/docbook/roff expert ...
