Re: url-retrieve bad handling of redirections

["Richard M. Stallman" <rms@gnu.org>]

	Adding a new parameter to the callback routine so that it still can have 
	the original outfile as a parameter. That way you could continue from 
	the redirect and change the redirected url instead of the original.

What do you think of this change?
Unfortunately it is not practical for me to study the code enough
to tell if this would break anything.
