tramp (2.2.2-pre); non-working "stat -c" no longer correctly handled or recorded in ~/.emacs.d/tramp

[Carsten Bormann]

Using tramp via ssh/scp to connect to a box that doesn't like "stat -c"
(such as OSX) aborts with the message:

byte-code: `\stat -c '("%N" %s)' /' returns with error

For long-time tramp users this is usually masked by an existing entry in
~/.emacs.d/tramp such as
  ("stat" nil)
so the bug is never triggered.

Apparently, the bug is recent and only occurs in recent versions of
Emacs 24, so you'll only detect it with trying out new hosts.
(or tricking out tramp by connecting to /hoStname: etc.)
