I've started myself to play with GNU enscript
(http://people.ssh.com/mtr/genscript/), which is a modularized
pretty-printer, with support for a good number of languages.  It does
not have a DocBook output definition yet, but it should not be a
problem to add one, and I may do that at some point it noone does that
first (which I'd welcome wholeheartly ;) - as well as a DocBook output
filter for noweb, FWIW.

However, it currently does HTML (although not conformant, see
http://bugs.debian.org/221513 where more patches should appear once
the current problems with the Debian servers are fixed).

For a demonstration of its use for pretty-printing embedded code in a
document, see http://ydirson.free.fr/en/software/noweb/dh-kpatches.html

This is done using noweb, with filters in
http://ydirson.free.fr/en/software/noweb/.  The actual pretty-print
filter (http://ydirson.free.fr/en/software/noweb/enscript-html) is
probably more complicated that what would be needed for a non-litprog
code snippet.
