GradientEverything breaks {\p0} at end of line

[petzku]

When gradienting drawings which end in {\p0}, the script removes the {. This doesn't affect rendering, but is probably unintended.

Sample:
{\an7\pos(0,0)\c&H65D0EB&\p1\blur1}m 702.34 540.33 l 746 488 448 470 508.23 541.74 450 612 606 799 762 611 702.34 540.33{\p0}
becomes
{\clip(195,204,200,359)\pos(0,0)\an7\c&H65D0EB&\p1\blur1}m 702.34 540.33 l 746 488 448 470 508.23 541.74 450 612 606 799 762 611 702.34 540.33\p0}
