recentf / custom-file

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

As suggested on Feb 13, this addresses a problem where the custom- 
file is sometimes added to the "recentf" list of recently opened  
files, when custom-file is a non-canonical filename such as "~/.emacs- 
customizations.el" and the options are saved.

Please apply the patch at your discretion.

	* cus-edit.el (custom-save-all):  canonicalize custom-file before
	storing it in recentf-exclude.
