Re: Long text in tbl won't wrap, maybe related to mom

[T. Kurt Bond]

I can't remember if the groff mailing list allows small attachments or not,
so I'm trying to attach the mom source I used (in a .zip so the tabs won't
get modified) and the output pdf it produces to this email.

Oh, and the slightly munged version of groff from git I was using
was 1.22.4.196-1d2d-dirty.

And here's the exact groff command I used and its output:

groff -t -Tpdf -mom x.mom >x.pdf
troff: x.mom:2: error: can't transparently output node at top level
troff: x.mom:13: warning [p 1, 1.5i, div '3tbd2,0', 0.0i]: cannot adjust
line
warning: file 'x.mom', around line 13:
  table wider than line width
warning: file 'x.mom', around line 8:
  table squeezed horizontally to fit line length


Can someone try and see if they can reproduce these results with the
current groff git source?
