You are right; all li, lin, line, linea, linear and lo, log combinations 
work.

Also on, of and off are correct answers for "on|off", and similarly for 
other string settings.

Furthermore, the set() command with two parameters only writes a list with 
all possible options, while Octave prints an error message intead of such a
help message:

	> set(h,'yscale');
	error: set: invalid number of arguments

vs.

	>> set(h, 'yscale')
	[ {linear} | log ]

This help message would be very welcome in order to actually know which 
options one can set.

It seems there is no documentation for various "set", right?

As the graphics compatibility seems to be one of the current main goals, I 
would propose to push this fix as soon as it is ready.
