It seems that changes introduced in r8218 drastically changed how `hist` handles Python lists.
For example, the histogram given by the following snippet, works as expected:
x = np.random.randn(100)
plt.hist(x)
However, if you pass a 1D list to `hist`, the 1D list is cast to a list of length-1 arrays---each treated as a separate histogram. Continuing the above code, check the results of the following:
plt.hist(list(x))
I assume that this behavior is unintended, right?
