Sorry, but that's false. Allow me to quote RFC 3986 section 3.1 about the
"scheme" part (which is what we're talking about here):

    An implementation should accept uppercase letters as equivalent to
    lowercase in scheme names (e.g., allow "HTTP" as well as "http")

I don't think that leaves much interpretation. Do you?

No it doesn't, so yes the results _could_ indeed be made consistent without a
major effort. The differences right now are simply because one of them are
added by the protocol guessing logic and the other by "repairing the URL after
it already knows which protocol it is".

I'm mostly saying this isn't a bug. I still agree that it would be nicer to
use the same lowercase name for all scenarios you show. A matter of niceness,
not correctness.

You feel like producing a patch?
