[Haskell-cafe] Renumbered mailing list posts

[Henning Thielemann]

Recently I found that links from Google search results to archive 
Haskell-Cafe messages are invalid. The messages are still there, but got 
a different number. E.g. the search result says:
   http://www.haskell.org/pipermail/haskell-cafe/2011-February/089455.html

But the message is at
   http://www.haskell.org/pipermail/haskell-cafe/2011-February/088146.html

Also links from Haskell-Wiki articles to the Haskell-Cafe archive are 
invalid now. This is very very very bad, since I used tons of such URLs 
in Wiki articles and it is very hard to find the message I referred to, 
if the URL does not work anymore.
