[matplotlib-devel] error in add_subplot

Current SVN (r6540) raise an error for the following code.


import matplotlib.pyplot as plt
import matplotlib.axes as maxes

fig = plt.figure()
ax = maxes.Subplot(fig, 1, 1, 1)
fig.add_subplot(ax)

It seems that some of the code Mike recently introduced in "figure.py"
have incorrect indentation, but I'm not 100% sure.
I'm attaching a patch which seems to work for me, and It would be
great if Mike or others review it and apply.
