Seems to be an apt "feature".  After patching it out with

diff --git a/methods/server.cc b/methods/server.cc
index e12c23c..e07599c 100644
--- a/methods/server.cc
+++ b/methods/server.cc
@@ -294,7 +294,7 @@ ServerMethod::DealWithHeaders(FetchResult &Res)
          NextURI = DeQuoteString(Server->Location);
          URI tmpURI = NextURI;
          // Do not allow a redirection to switch protocol
-         if (tmpURI.Access == "http")
+         if (1 || tmpURI.Access == "http")
             return TRY_AGAIN_OR_REDIRECT;
       }
       /* else pass through for error message */

I was able to get apt-get changelog to work.  My test case is

apt-get -o Acquire::ForceIPv4=yes -o Apt::Changelogs::Server=http://www.cristau.org/blah changelog tor

with a

RewriteRule ^/blah/(.*) https://packages.debian.org/changelogs/$1 [L]

in my apache config (the forceipv4 is needed due to unrelated breakage
at the hosting provider).
I still get a message like this, though:

W: Size of file /tmp/apt-changelog-TfnbZ1changelog is not what the server reported 77136 338

I guess something's keeping the size from one of the redirects instead
of the 200.

I couldn't get aptitude changelog to obey Apt::Changelogs::Server for
some reason, so I don't know if that's enough to fix it.

Cheers,
Julien
