Good point. I think in LyX there is an idea that we don't want to change
LaTeX defaults. LyX makes automatic preamble additions for
*dependencies* (like loading a required package), but I'm not sure we
change many defaults like this limit of columns. Do we?

However, I do think it would be nice to do something for situations like
this. What an ugly error that LaTeX gives in this example.

My personal opinion (and I would be surprised if all other LyX
developers agreed with me) is that if we aren't going to change the
default limit, at least we can give a user friendly message of "You
might get a LaTeX error... add this code to the preamble").
