I do not think the existing tests were checking anything interesting in
that respect. The url-matching code does not do the canonicalization,
and nor should it (the internal callbacks for all variables should use
the canonical lowercase version). So we were only testing that
test-url-normalize lowercased them, which is not something we actually
care about (nobody but the test script should ever call it).
That being said, git-config _should_ be lowercasing to match the normal
--get code path. I think the fix (squashable on top of 6/6 + my earlier
patch) is just:

I guess I don't understand why we have so many items in each file. That
is, we have:
"$tc-1" "useragent" "https://other.example.com/"; = "other-agent"
"$tc-1" "useragent" "https://example.com/"; = "example-agent"
The first checks that we do not apply within a sub-domain (but fall back
to http.useragent), and the second checks that we do properly apply the
full domain.
"$tc-1" "sslVerify" "https://example.com/"; = "false"
This check seems redundant with the second one above.
"$tc-1" "useragent" "https://example.com/path/sub"; = "path-agent"
"$tc-1" "sslVerify" "https://example.com/path/sub"; = "false"
Here we make sure paths are preferred over non-paths (the first one),
but that config keys with non-paths are still used (the second).
"$tc-1" "noEPSV" "https://elsewhere.com/"; = "true"
This seems redundant with the first test (check that we do not match and
fallback to http.noepsv).
"$tc-1" "noEPSV" "https://example.com"; = "true"
Not sure what we are testing here; there is no variable besides the
one in http.noepsv. Somewhat redundant with the first test.
"$tc-1" "noEPSV" "https://example.com/path"; = "true"
Ditto.
"$tc-2" "useragent" "HTTPS://example.COM/p%61th" = "example-agent"
"$tc-2" "sslVerify" "HTTPS://example.COM/p%61th" = "false"
Testing normalization, though they seem redundant with each other.
"$tc-3" "sslcainfo" "https://user@xxxxxxxxxxx/path/name/here"; = "file-1"
Testing specific pathnames preferred to usernames, which is useful.
I don't mean to nitpick. It was just hard as a reader to figure out what
specifically each one was interested in checking, which means it may be
similarly hard if one of the tests is later broken for the investigator
to figure out what was happening. I don't know if it is worth putting
each in its own test and annotating what each is looking for (it may
also help show gaps; e.g., we check that longer pathnames trump
usernames, but we do not check that the same pathname prefers the
version with the username).

Yes, that makes sense to me; all of the other config is in the t1300
series.
