So now we have a problem:  octave scripts only work with the call
to setvbuf(), while awk scripts only work without it.  Octave is likely t=
he
more important application, and anyway people have been using the
setvbuf() version for almost 2 years now.  So we should leave the
default the way it is.

However, in case someone does want to use an awk script,
perhaps there could be an option
=09set mouse [no]buffered
The default would be nobuffered, implemented by the existing call
to setvbuf(). Specifying 'set mouse buffered' instead would bypass
the call to setvbuf() and allow awk to work.=20

Would that be an acceptable work-around?
