As mentioned in #928, I have some improvements to pyplot which required an improved workflow for generating the pyplot script in the first place. These are those changes.

Firstly, I have added text wrapping in the pyplot module such that no autogenerated line is longer than 80 characters.

Secondly, I have fixed a bug where keyword passing is miss-handled (keywords were previously being passed as positional arguments), which is best demonstrated by the following example:

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


class MyAxes(maxes.Axes):
    name = 'myaxes'
    def imshow(self, *args, **kwargs):
        kwargs.setdefault('alpha', 0.5)
        maxes.Axes.imshow(self, *args, **kwargs)

mproj.register_projection(MyAxes)

plt.gca(projection='myaxes')
plt.imshow('my_img.png')

Resulting in the following error:

TypeError: imshow() got multiple values for keyword argument 'alpha'

Ooooh, I gotta test this one out. It might solve a problem for me in mplot3d.

Hmmm, it does not solve the problem I have for mplot3d's scatter() (I get an error message saying that multiple values for 'zs' is given for the invocation as plt.scatter(x, y, zs=z), and I get an error saying that multiple values for 'c' is given for the invocation as plt.scatter(x, y, z). Note that I don't expect the latter to work.

Are you sure? The following code works for me on this branch, but not for me on master:

import numpy as np
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt

ax = plt.axes(projection='3d')
n = 3

xs = np.random.randint(23, 32, n)
ys = np.random.randint(0, 100, n)
zs = np.random.randint(0, 10, n)
plt.scatter(xs, ys, zs=zs)

plt.show()

Huh, must have used the wrong branch or maybe the pyplot.py file didn't rebuild properly? It now works from a clean install. Neat!

We probably should make sure that all tests pass and that the examples in the documentation didn't break.

Should have said, I have done a test run and full documentation build before opening the PR.

Seems like there are no concerns so I will merge in ~18 hours (tomorrow morning for me).
