Bugs:

* .Xo/.Xc Berkeley macro needs work. See elf.5.

* Look at lwres_getaddrinfo.3 -- good type case for resuming function parse
  after text.  sox(1) and soxmix(1) show the same problem with command syntax.

* CA.pl.1ssl -- CA.pl is not properly tagged as a command.

* Why aren't the command synopses in ab.1 and ac.1 parsed correctly?

Edge cases in which we could do better --

* sox(1), soxmix(1)
    These are totally hosed.

* qurlinfo(3qt) and others:
    operator declaration is seen as text, not structured.

Other things to do:

* Stereotyped .in/ta/ti pattern in emacs.1

* Stereotyped .in patterns under DIAGNOSTICS in compress.1.

Big projects:

* Translate EQN.
