* Use "maybeDecompress" to handle broken proxies that transparenty
decompress network streams. Closes #622, #686. Cabal update could fail in
some cases, see http://trac.haskell.org/http/ticket/109283

So we now are quite tolerant, perhaps too tolerant. I'm leaving this
ticket open because I think the "right thing" is to be slightly more
paranoid. I think we should use the headers as described above to see what
we expect to happen. In the case that we expected it to be compressed but
it is actually not compressed, we should handle it as we do now, but
perhaps in an even more paranoid way (e.g. checking for gzip magic number,
checking for a valid tar header), and perhaps also emitting a warning
about the broken proxy.
