Fixed Bug #{2334}
Fixed Bug #{2334}

While using modeditor(n) in the testing and debugging of gramdb(n),
I realized that the UI needed some changes:

* The entry field for entering command names needed to be considerably
  longer.
* The confirmation dialogs need to have the "don't ask again" checkbox
  enabled.

This commit does that.
