* Noticed something that was technically correct but confusing: when viewing a wiki history, each line displayed the date and author of the diff, which is NOT the same thing as the date and author of the page you would get if you reverted to that version.  Configured some off-by-one logic in the display code to compensate for this.  As an added bonus, the last line, which simply displayed an empty message, has been replaced by a new first line, which displays the date and author of the current version.
