New description:
Right now, if you have a dashed arrow, the arrowhead is also drawn with a
dashed linestyle, which really looks bad. Compare before and after for
`arrow((0,0), (1,1), linestyle='dashed')`.
This code works around a design issue in matplotlib. Currently, the
specified linestyle is used to draw both the path and the arrowhead. If
linestyle is 'dashed', this looks really odd. This code is from Jae-Joon
Lee in response to a post to the matplotlib mailing list. See
