Sure.

Ah, I see.  So you're saying there's some method to the madness by which
it's decided which chapter() directives do, or do not, appear in the man page.

Furthermore, chapter() headings ("9. Functions") and sect() headings
("9.1 Autoloading Functions") are rendered the same way in the man page.
It would be nice to fix this.

Actually, if you look at the source, you'll find that all these
references are done separately for the man page output and for the
texinfo output.  This instance is typical; it looks like this:
.
    General shell syntax is introduced in ifzman(the section `Shell Grammar' in
    zmanref(zshmisc))\
    ifnzman(noderef(Shell Grammar)).
.
Therefore, we can easily change the text for the man page output only,
as a low-hanging fruit / hotfix.

I don't think you are.  What I know about yodl and the manual could fit
in a very small number of bytes.
