SQL Error in Custom Date Format

[Something_Smart]

This is a totally inconsequential thing but I figured it'd be better to post it than to not.

In the Custom Date Format field (Control Panel -> Board Preferences -> Global Settings), the character limit is 30 characters.

However, if you enter a double quote (") or an ampersand (&), it is counted as more than one character, which causes an SQL error if the total is over 30. Presumably this is because it is converted to " or & before the string is stored.
