check-ispell-version can't deal with gone directory

[Dan Jacobson]

Oh great, I can't read any files anymore, as all I get is:

(Next local Ispell command will use american dictionary) [2 times]
Starting new Ispell process...  check-ispell-version: Setting current
directory: no such file or directory, /proc/21822/

Just because some buffer I was using was associated with a now gone
directory.  Must restart emacs.

Seen as root with emacs-version"21.3.1"

P.S. "check-ispell-version should be called
ispell-check-ispell-version perhaps.
