Bug#711139: gnuplot-qt: the grid doesn't work with the 'qt' terminal

[Vincent Lefevre]

Control: retitle -1 gnuplot-qt: the grid doesn't work with the 'qt' terminal in -persist state

I recall the testcase:

$ GNUTERM=qt gnuplot -persist <<EOF
plot '-' using 1:2 t '' with line
0 0
10 10
e
EOF

However if instead of this testcase, I just start

  GNUTERM=qt gnuplot -persist

then enter the commands manually:

gnuplot> plot '-' using 1:2 t '' with line
input data ('e' ends) > 0 0
input data ('e' ends) > 10 10
input data ('e' ends) > e

then the grid button works. Then if I type "quit" to get the prompt
back, the window persists as required, but grid button no longer
works.

Note that the 'wxt' terminal doesn't have such a problem.
