We've discussed a number of times that eval_string is not the best way
to handle a fully interactive Octave session because it can't handle
partial commands.  Or has that changed in some way that I don't
remember, so that eval_string can properly process things like

  "if (some_condition)"
  "  do_something ();"
  "else"
  "  do_something_else ();"
  "endif"

as a series of separate lines?
