Username/password in the URL not decoded when used for basic authentication

首先使用提供的 HTTPie 命令复现该问题，并跟踪 URL userinfo 如何传入 basic authentication。当用户名和密码中的 percent-encoded 字符被解码用于身份验证，且复现返回预期的 200 响应时，工作即告完成。

Checklist

• I've searched for similar issues.
• I'm using the latest version of HTTPie.

Minimal reproduction code and steps

Run http https://u%40d:1%3d2%3f@httpbin.org/basic-auth/u%40d/1%3d2%3f.

Current result

401 status is returned because HTTPie tries to authenticate using u%40d username instead of the expected u@d (and wrong password, too, for the same reason).

Expected result

Same as from running http -a 'u@d:1=2?' https://httpbin.org/basic-auth/u%40d/1%3d2%3f, i.e. 200 status response.

Debug output

Please re-run the command with --debug, then copy the entire command & output and paste both below:

Additional information, screenshots, or code examples

I believe HTTPie should decode percent-encoded characters in the userinfo part of the URL. Curl does it and, well, it just makes sense: otherwise user names containing reserved characters simply can't be specified directly in the URL.

This is a minor problem, because using --auth works, but I think it's surprising and confusing that using them directly in the URL does not (at least it confused me).
