I don't understand: `M-x grep' does append null-device to the command
line (unless it's been set to nil).
With respect to compile, I posted a patch back in October 1996 that
defines a new variable (compile-disable-input) and sends an EOF to the
compilation process if it is non-nil (which it is, by default). I also
posted a compilation-mode-hook function (compile-enable-input) that
allows the user to run compilations that require input by emulating
comint-mode in the *compilation* buffer.
