[matplotlib-devel] dashed steps plot

Hi all,
   I ran into a problem where I wanted to plot a step-plot with dashed 
lines instead of solid lines which can be important for print media. 
This isn't possible with the current matplotlib version, so I added 
support for this. The patch is attached, but I didn't commit it yet 
since I wanted to ask for feedback first. It basically adds support to do

pylab.plot(x, y, 'steps--')

to create a step plot with dashed lines.
