C-x C-f \\localhost\share <return>
M-! dir <return>
;; => Opening process input file: invalid argument, //localhost/share/NUL:

When `call-process-region' calls `call-process', it passes NULL_DEVICE
for the INFILE argument. It should pass nil instead.  I’m not sure
why, but the error above doesn’t happen if default-directory is a path
with a drive letter.

(For some reason NULL_DEVICE is defined as "NUL:" in my `config.h'.)

Thanks, I installed what I hope is the obvious patch, as trunk
bzr 113439.  Please give it a try, as I don't use Microsoft Windows
and so haven't tested it there.
