documentation of "plot" mentions L fmt which doesn't seem to exist

Hi 

the documentation for plot says:
-----------------------
`L'
Set steps plot style. 
-----------------------
However, this doesn't seem to work:

octave.exe:49> plot([1,2,3],'L');
error: plot: properties must appear followed by a value
error: evaluating if command near line 58, column 6
error: evaluating if command near line 57, column 4
error: evaluating if command near line 55, column 2
error: evaluating if command near line 54, column 7
error: evaluating while command near line 41, column 5
error: evaluating if command near line 28, column 3
error: called from `__plt__' in file `D:\Program
Files\Octave\share\octave\3.0.0\m\plot\__plt__.m'
error: evaluating assignment expression near line 187, column 9
error: called from `plot' in file `D:\Program
Files\Octave\share\octave\3.0.0\m\plot\plot.m'

As 'L' doesn't exist for matlab either, I presume this is a remainder in the
documentation of an old Octave option.

Thanks

Kris

PS: I'm running 3.0.0 on Windows using handle-graphics, not gnuplot, but I
don't think that matters.
