Severity: wishlist
Tags: patch

I have defined in my .emacs an Ibuffer filter to list
the buffers running a process.

As others filters, you can get the via 'ibuffer-filter-by-predicate'
/e (get-buffer-process (current-buffer)) RET

I just find more convenient to have defined the new command; I bound
it to '/E' as a memo of 'E'xternal process, because '/r' and '/R'
are already assigned.

Do you want to add this into master branch?
