Flushed-out issue: "body argument(s) will be lost"

Flushed-out issue: "body argument(s) will be lost"

[Kristaps Dzonsons]

I notice, in running the new code over all manuals in existence, a great 
deal of this error.  It seems to come mostly from crap between `It's in 
column lists.  I investigated.  It's bad.  Real bad.

  .Bl -column atan_(y,x)_:=____  sign(y)_(Pi_atan2(Xy_xX))___
  .It Fn atan2 y x No := Ta
  .Fn atan y/x Ta
  if
  .Ar x
  \*[Gt] 0,

mandoc has been happily throwing this away.  Obviously this is wrong. 
It seems that `It' is in fact a multi-line block level even in columns, 
and that `Ta' can be invoked arbitrarily to add new columns.

If tabs can be used after within these bodies, I'm going to be unhappy.

I'll try to work on this a bit now before sleeping.  Gross.

It is essentially the printf(3) issue.

tabs yes, but .Ta will complain with new groff.
