Sorry for the delayed response.  I can't comment on the history of the line
style choices except to say they have been that way since I first started
working with PLplot in 1990 and I haven't touched them IIRC.  I personally
don't use them much -- solid & dashed (I think #3) lines is about it.  I was
never that impressed with the appearance of some of the higher numbered ones
either.

Since you're contemplating a change that (a) would look better but (b)
introduce backward incompatibility, one "nice" way to handle it would be
through line style "sets".  The legacy set would be 0, the new set 1.  Let it
default to the new set but use an API call to switch back to the legacy set.
That way you can also easily recover exact postscript results on test program
output when you're trying to isolate an output regression.

Just my two cents, I don't have a strong opinion either way.

Down with the British!  (happy 7/4 ;)
