[Groff] Re: Manuals in pdf format

    PS: A related thing is the use of `Chapter:' in the header line.  I
        consider this redundant; a simple number would be sufficient.
        Consequently, I would like to see @thissectionname, @thissecnum,
        and @thischapnum.

I added @thischapternum for use in headers/footers.

Doing the section stuff right requires using marks.  I will probably
never have the energy to implement that.  I put it on the TODO list and
hope someone else will be able to work on it someday.  Sorry.
