That would break some existing uses.
For example, if you want to continue writing to an output pipe but
change a characteristic such as the default font:

  set output '| display png:-'
  set term png font "verdana"
  plot <something>
  set term png font "Times" 20
  plot <something_else>


We are moving towards an alternative command that would let you 
do this without calling 'set term'
  set term png font "verdana"
  plot <something>
  set termoptions font "Times" 20
  plot <something_else>

But so far this only works for a small number of terminal options.

Hmm.  That comes closer.  I don't know if that test is sufficient or not.
What would happen in the case of "set term push" and "set term pop"?
[I've never gotten those to work as I expect anyhow, so maybe it would
be a small loss].
