+ # PO files breaks the meta plugin's parsing enough to save ugly titles
+ # to %pagestate at this time.
+ #
+ # Then, at render time, every page's passes on row through the Great
+ # Rendering Chain (filter->preprocess->linkify->htmlize), and the meta
+ # plugin's preprocess hook is this time in a position to correctly
+ # extract the titles from slave pages.
+ #
+ # This is, unfortunately, too late: if the page A, linking to the page B,
+ # is rendered before B, it will display the wrongly-extracted meta title
+ # as the link text to B.
+ #
+ # On the one hand, such a corner case only happens on rebuild: on
+ # refresh, every rendered page is fixed to contain correct meta titles.
+ # On the other hand, it can take some time to get every page fixed.
+ # We therefore re-render every rendered page after a rebuild to fix them
+ # at once. As this more or less doubles the time needed to rebuild the
+ # wiki, we do so only when really needed.
