Ft/Fn vs. parentheses weirdness

Hi!

I wanted to mark up a function like this:

int (*foo)(bar, baz)

using Ft/Fn. I noticed that I can't really do that, and found some
weird behaviour both with groff 1.19.2 and mandoc 1.13.0 (the newest I
have installed).

Can you please take a look at the attached test page and tell me

* if there is a way to do what I want?

* how many bugs I found? :)

For the record, this is what it looks like for me with groff:
# groff -mandoc -T ascii test.3 |less
test.3:24: environment stack underflow
test.3:24: cannot chop empty macro
TEST(3)                 NetBSD Library Functions Manual                TEST(3)

NAME
     test -- test page

SYNOPSIS
     Some weird Fn/Ft test cases

DESCRIPTION
   Case 1
     int
     bar(void)
     Function gets formatted even though inside a Bd literal.

   Case 2
     int (*foo()) bar baz

     Parentheses are in weird places, arguments are not taken as function
     argument.

   Case 3
     int Po(*foo)
     ) bar baz

     Loses Fn completely due to Po/Pc.

   Case 4
     int (*foo)(bar, baz)

     This is what I wanted, but the parentheses are marked up in bold.
