I like it, please commit it to cvs then ... with just some fix for:

I have found only this non-working ('bla' does not exist):
   plot x, 'bla'
   splot x*y, 'bla'

this gives no plot and:

gnuplot> plot x, 'bla'
                  ^
          warning: Skipping unreadable file "bla"
                        ^
          x range is invalid


I would prefer just the function x is plotted.
