dired: "!" How to see not just result, but !-cmd too?

[David Combs]

Problem: the dired "!"-cmd leaves only it's *output* in *Shell Command
Output*; sure be nice if it also left the *command* (and args) that
got *executed*.

So that if you come back to that buffer later on, there's
no question as to what !-cmd you did "way back then" 
to *create* the buffer!

Sure would be a lot more user-friendly!


Thanks,

David
