* How do I do _THIS_ with emacsclient?

Hi, I have the following problem: I try using something like
${EDITOR} --eval "(ediff-files (pop command-line-args-left) \
  (pop command-line-args-left))" "file1" "file2"

and when ${EDITOR} is equal to emacsclient, this fails pretty badly:
command-line-args-left is nil, and Emacs tried to execute file1 and
file2, leading to undefined variable complaints.

This behavior clearly is dissatisfactory.  Any idea what I could write
to have this more or less work with emacsclient without breaking when
using Emacs?

I don't know what to do about the argmunents not available with
`command-line-args-left' but why not use a simpler command like:
    ${EDITOR} --eval '(ediff-files "file1" "file2")'

Because file1 and file2 may not be properly quoted for use in Lisp
strings.

Is it a real problem or a principal one ?
For real life you can always do:
    ln -s "file1" /tmp/file1_$$
    ln -s "file2" /tmp/file2_$$
    ${EDITOR} --eval '(ediff-files "'/tmp/file1_$$'" "'/tmp/file2_$$'")'
    rm -f /tmp/file1_$$ /tmp/file2_$$

Ehud.
