Hi,

This patch prevents running an asynchronous empty command.  Should the
user mistakenly enter "M-& <RET>", it won't create and pop up an empty
*Async Shell Command* buffer.  It also has the nice property of not
erasing a previous *Async Shell Command* buffer if one user runs the
empty command.

I don't think this is much of a trouble for synchronous shell-command
because then it only displays the message "(Shell command succeeded with
no output)" in the minibuffer.
