 321  * Generates each row in the contributions list.

 323  * Contributions which are marked "top" are currently on top of the history.
 324  * For these contributions, a [rollback] link is shown for users with sysop
 325  * privileges. The rollback link restores the most recent version that was not
 326  * written by the target user.
 327  *
 328  * If the contributions page is called with the parameter &bot=1, all rollback
 329  * links also get that parameter. It causes the edit itself and the rollback
 330  * to be marked as "bot" edits. Bot edits are hidden by default from recent
 331  * changes, so this allows sysops to combat a busy vandal without bothering
 332  * other users.
 333  *
 334  * @todo This would probably look a lot nicer in a table.
