Please use

  strcmp (scale, "log")

instead.  If we modify Octave to accept the shortest case-insensitive
match for radio property values, we will also ensure that the property
value is set to the full value with lower-case letters.  So

  set (gca (), "yscale", "lin")
  set (gca (), "yscale", "linea")
  set (gca (), "yscale", "LIN")

etc. will all result in

  get (gca (), "yscale")

returning "linear".
