[bug #21331] FISH: Retrieving an unreadable file causes MC to hang

[G. Karageorgiev]

Follow-up Comment #4, bug #21331 (project mc):

I am sure. Later I replied that I checked out from the CVS because I could
not download the patch.

What I forgot to tell in my previous comment is that the attempt to view a
remote unreadable file is ignored and the remote unreadable directories appear
empty. Error panels are displayed however, when these attempts are done on a
local file system.
