Yes, I know. My question was more rhetorical, as in "what _should_
happen". It seems unfriendly not to do at least some basic
canonicalization with respect to encodings.

Yeah, sorry, that was a bad example, because a missing port is not
"do not care", but rather "default port". A better example is:
[http "http://p...@example.com/"] foo = 1
[http "http://example.com/path/"] foo = 2
If we see the URL "http://p...@example.com/path/foo", I would expect the
second one to match (it does not under a pure-prefix scheme). If we were
to make it match, you cannot say which of the two entries is "more
specific" they are both specific in different ways.

I'm not sure I agree with this. The URL handed to git is not always
typed directly by the user. E.g., it might be cut-and-paste from an
email or website, or it may even be fed by a script (e.g., the "repo"
tool will pull URLs from its manifest file).

But the user has to worry about last-one-wins anyway for same-length
prefixes, as you noted below.

Sure, I think yours is less surprising in this case. But it is more
surprising in other cases, like ones where URL encoding or optional
components are involved. E.g., imagine your two options above were
flipped (you do not usually verify ssl, but it is very important for you
to do so against cacert.org). An automated tool like repo tries to clone
from https://u...@cacert.org, and you might be surprised that SSL
verification is not turned on.

Ah, you're right. Sorry for the noise.
