Add optional PEP8_VALIDATE env flag for running prettier output from
tests into pycodestyle. If pycodestyle returns any errors, the test
fails.

Adds pycodestyle as a vendor dependency.

Several tests currently fail with the PEP8_VALIDATE flag enabled.

Proof of concept for #1.

Fixes #18.

Fix #60. Use same logic as prettier's printer-estree.js "Program"
case.

Fixes #58.

This diff escapes line breaks used with `assert` and indents the wrapped portions.

This diff handles Python 2's de-sugaring of a single `with` block's items into multiple nested AST nodes and is able to distinguish that case and reproduce accurate output based on the input code. It also handles wrapping long `with` blocks with many items.

Fixes #51

To be consistent with PEP8, set the default column margin to 79 characters. Add tests to check that 79 characters fits on one line but 80 characters breaks to another line.

Fixes #14

* Fail tests when encountering unknown node types

Before, a basic test added for a new node type would not fail, since the default behavior for a node would be sufficient. While more advanced tests *would* fail (because the desired formatting behavior didn't happen), it still seems useful to have tests assert that all seen node types are known.

I tested this by adding a test for a new node type (in a different diff) and seeing that the test failed as expected after making this change. I ran `yarn prettier` on the test file and saw that, while it complained about an unknown node, it didn't fail.

* Revert "Use options rather than globals."

This reverts commit 2d315d8.

* Use env var rather than manually set globals.
