Exactly.  So don't set a new hard limit of 100.

This would _always_ wrap lines to 100 columns when
80 columns is still preferred.

Imagine using a 100 column limit where a statement still
fits on 2 lines.  Now imagine the same statement wrapped
at 80 columns still fitting on 2 lines.

Which would you prefer and why?
