* Display a list of recent changes made by a user.
*
* This action can be used to display a list of pages modified by a specific user. It
* accepts a user value both as an action parameter and as a GET parameter. The
* specified user must be an existing user. If no user parameter is specified
* or the specified user is invalid, an error message is printed. If no user parameter
* is specified or the specified user is invalid, and the current user is logged in,
* the action will display a list of pages recently changed by the current user.
