with all due respect, those aren't functions, they're function pointers 
(as structure members). Therefore, if anything, they should be notated 
as (*func)(). But I tried that (with the new patches), and they weren't 
detected and emboldened (that's not a word, I know) in the html.

So I left them as-is.

I don't pretend to be a guru on this markup, but if there's a way to 
make symbol names fixed-width and bold, I'll gladly do it. But I 
disagree on turning these into functions, because that's not what they are.

The lines between the bulleted items will go, yes. Not the ones around 
the leading text of each list (which are necessary to delineate the lists).
