The wiki could be configured to use /haskellwiki/index.php?.. urls for
diffs (I believe this can be done by changing $wgScript). Then
robots.txt could be changed to
> Disallow: /haskellwiki/index.php
Which bans robots from everything except normal pages.
that sounds like the most promising approach to me (meta tags
for history pages already have noindex,nofollow; so that didn't
help, it seems? also, fewer robots look at meta tags than at
robots.txt).
