While tracking down why I could not access my MC repository at
http://www.heeg.de/~hmm2/mc/ anymore, I found that the ~ character
obviously gets escaped twice:
First in HierarchicalUrl>>printOn: (Version topa 5/5/2010 13:47)
An then in HTTPSocket class>>httpRequest:url:headers:content:response:
(Version ar 7/10/2010 13:53)

One of those should be removed. Since it is unclear to me which sone
should go, I can not provide a fix.

Cheers,
Hans-Martin
