Drupal 7: Converting a text field to a long text (aka textarea) field

Realize later on that text field you created needs to actually be a long text field?  You’re not alone.

After doing some research, I found zero complete solutions.  The ones I found leave problemattic remnants in the database, which can cause hard to diagnose issues such as restricted field length.  See references.

Luckily for you, the drush script below will do a more complete conversion.

Thanks go out to the references though, for getting me started.
