[Kst] Problem using KST from Command Line

[Barth Netterfield]

Hi, Roger,

I think that what has happened is that you are using custom column names 
(reading them from the 1st line of the file).

So I think if you do 

kst2 simple.dat -x x -y y

it will work.

thinking out loud:

This might be the correct behavior, in which case we should just fix the 
documentation.

Another option is to make 1, 2, etc an alias for the appropriate column from 
the command line.

hmmm

thanks for reporting this.
