FS#1092 displays "external edit" in oldrevs & pageinfo-footer for last edit

Over the past few days I have noticed an odd behavior with revisions on http://wiki.splitbrain.org/ for some pages.

In the "Recent changes" page, it will display the page and the IP that made the editing, but if you go to the revision history for that page it will display the last edit as an "external edit". Similarly it will say "external edit" in the tpl_pageinfo generated footer if you view the latest revision of the page. Note that this is not the case on all pages, nor is it necessarily something that haunt specific pages continuously.

At the time of writing, the following pages showed this behavior: http://wiki.splitbrain.org/wiki:plugins?do=revisions http://wiki.splitbrain.org/wiki:features?do=revisions http://wiki.splitbrain.org/wiki:users?do=revisions - Possibly a lot more, these were just the ones I caught in the first page of "Recent changes".

In case the pages above does not show the issue when you review this bug-report, I attached 2 screenshots.
