We should fill up the space after execution of an "rm", "cp" etc.

Question is - what files do we show?  What I'm leaning towards here is to
show the user what changed as a result; it's less interesting where they
are now. 
Some cases to think about:

cwd: /home/walters/tmp 
cmd: rm foo.png

Result here is clear: we should re-list /home/walters/tmp.

cwd: /home/walters/tmp
cmd: rm ../foo.png

Principle above would say re-list /home/walters.

cwd: /home/walters/tmp
cmd: rm foo.png ../bar.png

Both /home/walters and /home/walters/tmp?

cwd: /home/walters/tmp
cmd: mv foo.png ..

Both?  Or just /home/walters/tmp?
