In Japanese BBS of gnuplot, the following problem is reported:
The script
set term emf
set output 'temp.emf'
set arrow from -8,14 rto 5,-5 head size 5,20 empty lt 1 lw 6
set arrow from -8, 9 rto 5,-5 head size 5,20 filled lt 1 lw 6
plot x w p lt 1 lw 6 pt 4 ps 2 , \
x+3 w p lt 1 lw 6 pt 6 ps 2
makes thin circle points (not lw 6) and thin arrow stem (not lw
6). But they have thick lines on other terminals.
Attached patch may fix it.
I introduce screenshots:

First one is by gnuplot-4.6.3, 2nd one is by CVS version with my patch.
