Subject: [PATCH 3/3] disabling --persist because on our arm board it confuses
 things

with --persist enabled even something basic like

 seq 5 | feedgnuplot --terminal dumb

does not work. feedgnuplot simply sits there doing nothing. This is likely a
gnuplot bug. Those boards run an older gnuplot build, and I can't easily install
a new one to test. It's possible the newer gnuplots fix this, but it's easier to
release a new feedgnuplot instead
