[pstricks] Problem with pst-pdf?

[McGarry Vince]

I've noted a problem with pst-pdf (I think); I don't think the  
problem is with psgraph nor with the script I'm using. See the  
examples below.

The following compiles using Latex.

%%%%% Example 1

\listfiles
\documentclass{article}

\usepackage{pst-plot}
\usepackage{pstricks-add}

\begin{document}
\psset{llx=-0.8cm,urx=0.5cm,lly=-0.5cm,ury=0.5cm}
\psgraph(0,0)(0,-4)(20,4){\linewidth}{6cm}
\psset{algebraic=true}
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0.01}{20}{ln(x)}%
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0}{20}{cos(x)*2.71^ 
(-x/10)}
\psplot[linecolor=blue,showpoints=true]{0}{20}{cos(x)*2.71^(-x/10)}
\endpsgraph

\end{document}

%%%%%

Using the script attached at the end, the following fails with error

Runaway argument?
linewidth=4\pslinewidth ]{0.01}{20}{ln(x)}\psplot [linecolor=yellow,l 
\ETC.
! File ended while scanning use of \psgraph at ii.

%%%%% Example 2

\listfiles
\documentclass{article}

\usepackage{pst-pdf}
\usepackage{pst-plot}
\usepackage{pstricks-add}

\begin{document}
\psset{llx=-0.8cm,urx=0.5cm,lly=-0.5cm,ury=0.5cm}
\psgraph(0,0)(0,-4)(20,4){\linewidth}{6cm}
\psset{algebraic=true}
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0.01}{20}{ln(x)}%
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0}{20}{cos(x)*2.71^ 
(-x/10)}
\psplot[linecolor=blue,showpoints=true]{0}{20}{cos(x)*2.71^(-x/10)}
\endpsgraph
\end{document}

%%%%%

but the following works using the same script:

%%%%% Example 3

\listfiles
\documentclass{article}

\usepackage{pst-pdf}
\usepackage{pst-plot}
\usepackage{pstricks-add}

\begin{document}
\begin{pspicture}(0,0)(20,8)
\psset{llx=-0.8cm,urx=0.5cm,lly=-0.5cm,ury=0.5cm}
\psgraph(0,0)(0,-4)(20,4){\linewidth}{6cm}
\psset{algebraic=true}
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0.01}{20}{ln(x)}%
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0}{20}{cos(x)*2.71^ 
(-x/10)}
\psplot[linecolor=blue,showpoints=true]{0}{20}{cos(x)*2.71^(-x/10)}
\endpsgraph
\end{pspicture}
\end{document}

%%%%%

and the following works with either the pspicture wrapper or without:

%%%%% Example 4

\listfiles
\documentclass{article}

%\usepackage{pst-pdf}
\usepackage{ps4pdf} % deprecated, but works where pst-pdf fails
\PSforPDF{%
\usepackage{pst-plot}
\usepackage{pstricks-add}
}

\begin{document}
\PSforPDF{%
%\begin{pspicture}(0,0)(20,8) % not needed when using ps4pdf.sty
\psset{llx=-0.8cm,urx=0.5cm,lly=-0.5cm,ury=0.5cm}
\psgraph(0,0)(0,-4)(20,4){\linewidth}{6cm}
\psset{algebraic=true}
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0.01}{20}{ln(x)}%
\psplot[linecolor=yellow,linewidth=4\pslinewidth]{0}{20}{cos(x)*2.71^ 
(-x/10)}
\psplot[linecolor=blue,showpoints=true]{0}{20}{cos(x)*2.71^(-x/10)}
\endpsgraph
%\end{pspicture}
}
\end{document}

%%%%%

This is the script I use. (Herb Schulz's ps4pdf.engine)

%%%%%

#!/bin/sh
basefname=$(basename "$1" .tex)
# process the figures
latex --shell-escape "$1"
dvips -Ppdf -o "${basefname}-pics.ps" "${basefname}.dvi"
ps2pdf13 -dAutoRotatePages=/None "${basefname}-pics.ps" "${basefname}- 
pics.pdf"
pdfcrop "${basefname}-pics.pdf"
/bin/mv "${basefname}-pics-crop.pdf" "${basefname}-pics.pdf"
/bin/rm "${basefname}-pics.ps" "${basefname}.dvi"
#process the file
pdflatex --shell-escape "$1"

%%%%%
