This is not a bug. The exit status of `ls' can vary, depending on
whether or not it's killed by SIGPIPE or manages to write all of its
output before exiting. When it's killed by SIGPIPE -- writing to a
pipe with no reader -- the exit status is 141. When it completes
writing its output, the exit status will be 0. The same goes for
`tr'.
