* tmac/trace.tmac: Much improved.

(trace-full): New register to be set on the command line; it
controls whether number and string register assignments get traced
also.
(!!c): New macro for comments.
(rm): New traced macro.
(de, de1, am, am1): Use \\[xxx]\\ calling method to pass \$0 to
`!!xxx'; this makes doc.tmac completely traceable.
Trace call of .de and friends also.

* tmac/groff_tmac.man, NEWS: Update.
