[including plothsizes in src/test/in/graph among other places]

This safety measure is not needed in that file (no plotdraw there, we only
write to the virtual window or to pari.ps), and breaks the "graph" bench,
e.g if no connection can be made to an X server. No need for a formal
patch, just disregard what make bench tells you about "graph" if it looks
related to this problem (or to extra spacing around the plothsizes command)
