Several questions:

1) The section on range constants says that:

	Octave does not convert range constants to vectors unless it is
	necessary to do so.

When would it NOT be necessary to convert a range constant to a vector?  Would
an example be, say, a for loop?

2) Is there a way to subscript a constant range, e.g.

	[2:2:10](2:4)

as opposed to having to assign it to a dummy variable:

	a = [2:2:10];
	a(2:4)

3) The operators .+ and .- don't seem to work, as documented in the manual (of
course, they ARE redundant with + and -).  Have they been disabled?
