url-cache - (require 'url)

[David Reitter <david.reitter@gmail.com>]

I think url-cache.el needs a (require 'url) to define url- 
configuration-directory which is (now) needed to define url-cache- 
directory. Otherwise, a simple (require 'url-cache) fails unless url  
isn't loaded beforehand.

--Lisp error: (void-variable url-configuration-directory)
   (expand-file-name "cache" url-configuration-directory)
   eval((expand-file-name "cache" url-configuration-directory))
   custom-initialize-reset(url-cache-directory (expand-file-name  
"cache" url-configuration-directory))
   custom-declare-variable(url-cache-directory (expand-file-name

directory :group url-file)
   require(url-cache)
