codes in autopep8 documentation do not match pep8 documentation

[morgana2313]

The codes documented under Features do not match with the pep8 docs. I don't know if this is a glitch in the documentation or intentional.

Features:

• E101 - Reindent all lines.
• E121 - Fix indentation to be a multiple of four.

Pep8 docs:

• E101 | indentation contains mixed spaces and tabs
• E111 | indentation is not a multiple of four
• E121 (*^) | continuation line under-indented for hanging indent
