Listing process status in buffer list

[Richard Stallman]

    By the way, in various buffer lists
    .*  *compilation*      58  Compilation
    should also mention if its process is running or not, I suppose along
    with shell window listings, etc.

That is a good idea, and would not be hard to implement if
list-buffers is taught to look in some new buffer-local variable for
some extra text to put at the end of the line.

Would someone like to do it?
