system_settings_form() has an extra parameter; without it, default values are filled in for you automatically from system variables: http://api.drupal.org/api/function/system_settings_form/7
system_settings_form($form, $automatic_defaults = TRUE)

Needs includingin http://drupal.org/update/modules/6/7 with any extra details.

This should be filed as a reopening of the issue where the function was actually changed (setting the status to "Needs work" and adding a tag "Needs Documentation").

Will have to do some research to find the original issue...

Here's the real issue, which is still in progress, which is why it hasn't been documented yet. I have added the needs doc tag to the issue, and am closing this issue as a duplicate.
