  I watch the output, and hit control-X to cancel the third command if
the second command fails.

  I know it isn't necessary.  I can type in a command, press return,
wait for it to finish, type another command, press return, wait for it
to finish, ....  But it's much faster to use typeahead.  Having it
echo in the middle of my output is quite annoying, though.  (Then
again, I worked with Apple ][, IBM-PC, and VMS systems--which have
typeahead working "right"--before I worked with UNIX; maybe one gets
used to this weirdness eventually.)
  Does anyone know the original reason for the immediate echoing?
