a patch for giving limited number of points along a line

[KH.Moriyama <khm...@gm...>]

Hi.
I am a long user of gnuplot but new to this ML.
I want to inform about my patch. (the attached)

It adds a functionality "pointnumber" or "pn", which puts points
along a line drawn by "linespoints" by given number of points.
The result is similar to "pointinterval".
But, it is more convenient because user can directly give
the number of points appearing along a line without
knowing the exact number of data points that makes the line.

The position starting to put points is moved randomly to avoid
overstruck points.
A negative number for the point number works as same as
pointinterval, put spaces in the line at points.
It returns error in case both "pi" and "pn" are specified.

I hope it is useful for everyone.
