%%black will not format cell with magic in it

[mborus]

When formatting cells with magic in it, like

  [...]
  import matplotlib.pyplot as plt
  import seaborn as sns
  import pandas as pd
  %matplotlib inline

the %%black magic returns the error
cannot parse: 12:0 %matplotlib inline

This happens with any line that has a % sign to indicate magic.
