recentf-cleanup, file-readable-p & remote files

[Jesper Harder]

In GNU Emacs 21.3.50.32 (i686-pc-linux-gnu, GTK+ Version 2.0.2)
 of 2003-09-08 on defun.localdomain
configured using `configure '--with-gtk''

If my machine isn't network connected `recentf-cleanup' signals an
error when I turn on recentf-mode in my .emacs and I have opened
remote files (with ange-ftp) in the previous Emacs session.

1. `recentf-cleanup' should probably test with `file-remote-p' before
   calling `file-readable-p' on files.

2. Shouldn't `file-readable-p' [1] return nil in this case rather than
   signal an error?


[1] and `file-exists-p' etc.
