Problems with "set linetype cycle" in gp5 rc3

[Philipp K. J. <ja...@ie...>]

Consider the following commands:

	set linetype 1 lw 1 lc rgb "red"
	set linetype 2 lw 2 lc rgb "black"
	set linetype cycle 2

I expected alternating thin red and thick black
curves. But that's not what happens...

A command like:
	plot sin(x), cos(x), airy(x), 1/(x**2+1), -exp(-x**2)

plots the first and second curve as expected,
but then falls back to predefined line types,
until line type 8.

Only beginning with linetype 9 and 10 do I see
the alternating red/black lines. (This can be
clearly seen when running the "test" command.)

I first thought this was a bug, but then I saw
a line in the documentation: 

  If the line properties of a higher numbered 
  linetype are explicitly defined, this takes
  precedence over the recycled low-number 
  linetype properties.

So, I need to precede everything with

	unset for [i=1:10] linetype i

to remove the default line types.

That strikes me as rather odd behavior. I would
have expected that "set linetype cycle" takes
precedence.

Best,
