fixed userinfo regex for @ character in userinfo

[cansarigol]

USERINFO_RE regex pattern separates URL by first @ character. I changed this pattern to evaluate the last @ character so that can use an email address for userinfo.username (e.g. "https://[email protected]:[email protected]")

HI @sethmlarson could you review this pr.

There's no description for why this is important. All it says is that it "Fixed" something which is correct per the ABNF.

This fix about using email address for userinfo.username
e.g. "https://[email protected]:[email protected]". Email address is quite used as a username. But using in url I'm not sure. Hence I don't know how important it is.

in Httpx project we had a problem with this (issue328) and as per ticket, @sethmlarson wrote that we can fix rfc3986. Because of that, I wanted to push a commit to fix this problem.

As far as I understood, USERINFO_RE regex pattern separates URL by first @ character. I changed this pattern to evaluate the last @ character.

That's all great context that belongs in the commit message and pull request description.

Can we get it merged?

This is still not compliant with the RFC. The @ in the email must be encoded for it to be passed correctly
