Comment:
Kind of lame, but hoping to make up for it with clever points:
{{{
sage: dashed = arrow((0,0), (1,1), linestyle='dashed')
sage: dashed.show(filename='dashed.eps')
}}}
The EPS format calls `[6 6] 0 setdash` to enable the dashes, and `[] 0
setdash` to disable them. Before the patch, we enable the dashes, stroke
two objects, and then disable them:
{{{
gantu ~ $ cat dashed.eps | tr '\n' ' ' | grep -P -q
'setdash.*stroke.*stroke.*setdash'
gantu ~ $ echo $?
0
}}}
After the patch, we enable the dashes, stroke one object, and then disable
the dashes:
{{{
gantu ~ $ cat dashed-patched.eps | tr '\n' ' ' | grep -P -q
'setdash.*stroke.*stroke.*setdash'
gantu ~ $ echo $?
1
}}}
