Spin-off of #239825: drupal_mail(), CRLF, and Windows:
Right now, Drupal core has a heck of a lot of these hidden variables designed for ultra power users who want infinite control over things for which we can't really justify cluttering the UI to expose a setting for. We document some of them in default.settings.php, but since that file is more than long enough, we should not bother cluttering it with every single one-off variable.
To solve exactly this problem for global variables, we created a globals.php file which documents all of these and what they're for.
We should make a similar 'variables.php' to document at least the hidden variables.

webchickI'm going to downgrade this from critical. While it's still very important, this is something new we've never had before. This makes the lack of documentation around variables not a regression, so I see no reason for it to block release.
