axis.get_ticklines() only returns lines for major ticks


I have recently started to make plots with matplotlib. It's a great tool!
When trying to change the width of ticklines, I noticed that
axis.get_ticklines() only returns the line2D objects for the major
ticks. But one might want to change the linewidth of the minor ticks.
Hence, I propose something like

    def get_minor_ticklines(self):
        'Return the minor ticklines lines as a list of Line2D instance'
        lines = []
        for tick in self.minorTicks:
        return silent_list('Line2D minor ticklines', lines)

in class Axis. What do people think?

Also note, that, in fact, ticks are 'markers' and one has to change the
markeredgewidth (mew).
