Please suggest syntax for new command

[Ethan A M. <merritt@u.washington.edu>]

I've coded up a fairly trivial option that selects 
successive line *styles* for plots rather than successive
line *types*.  That would answer many requests over the years
for user control over the order of colors, etc,
without having to re-write all the corresponding plot commands.

Amazingly enough, this requires only about 6 lines of code.
However, it also requires some command to turn it on or off.
What should such a command look like?
I'm using as a test:

	set style preferences {ls|linestyle|lt|linetype}

where "preferences" can be abbreviated down to "pref".
I'm totally open to other suggestions, though.
Maybe   set style plot ...

There are a couple of other trivial user preferences that could
be stuffed into such a new style type, whatever it would be called.
None are very important, but have been requested from time to time.
E.g.	line spacing of multi-line text
	key titles in black/color
	max number of linetypes used before recycling
	text comment to be stored in the output	file if possible
