Legend for circle+line types

Deat Matplotlib Users,

I have to plot the frequency response of many filters on one
plot, and have to take a printout, necessarily black and white. Now, I
would like to use symbols at frequent intervals as well, for easy
distinguishing. Now, I wanted to know whether it is possible to have
the legend show both the line and the type of dot (such as square and
dotted line, circle and dot-dash) on a _single_ legend entry. Though I
am able to show the symbol in the legend, it would be nice to have
both shown as a single entry.
