Bug report

Bug summary

There is some very frustrating inconsistencies in keyword arguments names across the library. One notable (to me) example is "ncol" and "ncols" as found in matplotlib.gridspec.GridSpec and matplotlib.axes.Axes.legend, respectively.

Not a big issue, but I'm sure I'm not the only one consistently getting mixed up!
