Comment 1 for bug 1003633

Also, this 2007 thread:

[1] https://forums.aws.amazon.com/thread.jspa?threadID=16361

where AWS representatives expound on their "justification" some more.
Instead of being well-behaved netizens, they just document their
non-conformance – though there is no indication in these threads where
such documentation is, other than provided in examples.

That thread also indicates that the path is expected to be
URL-encoded, not just some characters. This probably means including
':' and others to avoid more unanticipated transforms.
