Details:

The tbl "nowarn" option within a .TS/.TE region disables 3 of the 4 possible
warnings that can be emitted when *roff formats the table.  These 3 all have
to do with potential horizontal truncation or ugliness of the table.

The fourth has to do with _vertical_ truncation or ugliness, and is
unconditional.

Should the semantics of "nowarn" be broadened to cover this last type of
warning?
