Fixes: T} can be followed by a delimiter then more data. Make this

work and add documentation for it.

Also make tbl_term() not puke if the number of data cells is less than
the number of layout cells (which happens from time to time).  This
still needs work because we should pad out empty cells so that the
borders all work out.
