[groff] pdfpic.tmac

[Heinz-Jürgen Oertel]

Hello,

I'm using groff and -Tpdf and pictures included with .PDFPIC.
PDFPIC always crashes. The reason is, that pdfinfo has in its stdout text not 
only text but also a '\0' char. The effect is, that pdfinfo | grep gives an 
error message instead of the line containing the measurements.

What I did, is adding --text to grep, like 

.sy pdfinfo @$1 | grep --text "Page *size" | ..

guilty is pdfinfo
$ pdfinfo -v
pdfinfo version 0.66.0

But anyway adding --text is a good workaround
