    _______________________________________________________

Details:

On octave control pkg (vesion control-2.6.4).

rlocus function, if no output arguments are requested, plots the Root Locus
diagram. To do that it:
- invoke 'plot' (line 288)
- set the current figure to not visible (line 289)
- invoke 'plot' again (line 290)
- modify certain parameters
- makes the figure visible again (line 304)

I think that this procedure in unnecesary and interfere whith non interactive
invocations to Octave (used directly to print graphics results)

So lines 288, 289 and 304 should be removed.
