OK; will change it back.

Not terribly; the code is already _mostly_ in place
to handle this.  The only troublesome area is error
recovery: if you set -columns to something that's
incompatible with -displaycolumns, it raises an
error (which is OK) and leaves the widget in an
inconsistent state (which is not).

This is a recoverable condition and won't lead to
any crashes, but it violates one of the invariants
that widgets are supposed to maintain.
