Hi,

Enclosed is a patch that considerably simplifies and improves the 
handling of literals in -man.  I've implemented it for all frontends but 
would like a bit of testing, first.

Basically, it pushes LITERAL mode handling directly into the 
print_man_node() functions instead of scattering them here and there 
(except where we need to manually unset it).  It's a lot clearer than it 
was before, and in my few tests, works much, much better.

Thoughts?
