The following patch places the Exit code in the mode line of the
*Shell Command Output* buffer (using the `mode-line-process' variable).

So it's shown to the users interested in such things, but don't
mess with the buffer...

What do you think? 

(The following patch was inserted here with insert-buffer without
manually having to delete the ...Shell command failed  line :-)
