[pstricks] bug in pstricks-add BETA: \readdata needs ignoreLines

[Patrick Drechsler]

Hi,

just wanted to let you know that when using the current
pstricks-add *BETA*[1] the new option "ignoreLines" can't be
omitted.

Minimal example (taken from page 87 of pstricks-add-doc):

--8<------------------------schnipp------------------------->8---
\listfiles
\documentclass[12pt]{article}
\usepackage{pstricks-add}
\begin{filecontents*}{pstricks-add-data9.dat}
some nonsense in this line äöüÖÜß
time forcex forcey
0 0.2
1 1
2 4
\end{filecontents*}
\begin{document}
\readdata{\data}{pstricks-add-data9.dat} % <- error
% \readdata[ignoreLines=2]{\data}{pstricks-add-data9.dat}
\pspicture(2 ,4)
\listplot[showpoints=true]{\data}
\psaxes{->}(2,4)
\endpspicture
\end{document}
--8<------------------------schnapp------------------------->8---

This results in following error message:
