tex-compile problem if tex-start-commands is nil.

[Markus Rost]

I tried the new C-c C-c in tex-mode, and got an error.  The reason is
that I have set tex-start-commands to nil, and so

(shell-quote-argument tex-start-commands)

in tex-compile-commands returns an error, when evalled.  I see several
possibilities to fix this, but I am not sure which to choose, so I'll
leave it to Stefan.  ;-)
