options_per_line defaults set by upgrade script prevent edits to text and date custom fields

In the script that upgrades the MySQL database from 1.1 to 1.2, there's a line that adds the options_per_line field to the civicrm_custom_field table:

ALTER TABLE civicrm_custom_field ADD options_per_line int unsigned DEFAULT 1 COMMENT 'number of options per line for checkbox and radio';

Here, the default for the field is set to "1." This is fine for custom fields that are checkboxes or radio buttons. However, for date and text custom fields, if options_per_line is set to "1," the text or date fields are not shown when editing custom field data in CiviCRM, or when conducting advanced searches.

Changing options_per_line back to "0" for text and date fields fixes the problem.

I'm not sure how select fields are affected by options_per_line being set to "1," so you might want to check on that as well.
