With ls it's reasonable, but the following is something that drives me
crazy.  Try it with a 1-line file, foo:

  tail -f foo | more             works
  tail -f foo | grep .           works
  tail -f foo | grep . | more    doesn't work

Looks like grep has different behaviour depending on if stdout is a
tty?
