url-basic-auth -- default user/password prompt to values from URL

[Edward O'Connor]

Hi all,

I've been hacking a bit on some code that uses url.el to talk to a
website which uses HTTP Basic authentication. I'm specifying the
username/password combination in the URL itself, and yet
`url-basic-auth' prompts me for my username and password.

Fixing that looks potentially complicated, so I thought an incremental
improvement would be for the prompts to pre-populate with the URL's
username/password combo. A patch is attached that does just that. It
would be great if this made it in before 22.2.

Here's a ChangeLog entry:

2007-08-04  Edward O'Connor  <address@hidden>

        * url/url-auth.el (url-basic-auth): When prompting for username
          and password, default to the username and password in the URL.
