[vdr] Grab command from 1.3.38 Changelog misses a "-"

[Philippe Gramoullé]

 Hello,

After i just upgraded to 1.3.38 (again, congratulations to Klaus and all contributors),
i wanted to grab a picture using the command included in the Changelog:

svdrpsend.pl -d <hostname> 'grab -'  | sed -n -e 's/^216-//p' \
-e '1ibegin-base64 644 -' -e '$a====' | uudecode | display

The final command "display" misses the standard input "-" to work correctly.

svdrpsend.pl -d <hostname> 'grab -'  | sed -n -e 's/^216-//p' \
-e '1ibegin-base64 644 -' -e '$a====' | uudecode | display -

And now it works wonderfully ;)

Thanks,

Philippe
