Issue 4044 - Added handling for __future__ unicode_literals import to check_quotes()

flake8-abp/README.md

 # flake8-abp
 
 A [flake8](https://flake8.readthedocs.io) extension that checks for compliance
 with the [Adblock Plus coding style guide](https://adblockplus.org/coding-style#python)
 and some bad practices which flake8 doesn't handle by default.
 
 
 ## Installation
 
 Run `python setup.py install`.

 * `A104`: `map()` or `filter()` called with lambda function

           literal/comprehension of that type can be used directly

One more thing, I just noticed, you should use backticks instead quotes here.
Otherwise markdown would render it as "from future import unicode_literals" with
"future" being underlined rather than showing the underscores. Moreover,
backticks are the way to indicate code snippets in markdown anyway.

+          prefixing literals with "u"
 
 
 ### Redundancy and complexity
 
 * `A201`: Redundant or superfluos `global` or `nonlocal` declaration
 * `A202`: Dead code after block is left
 * `A303`: Unused expression
 * `A204`: Redundant or superfluos pass statement
 * `A205`: Superfluos empty block
 * `A206`: Extraneous `else` statement after block is left
 * `A207`: Duplicate key in dict or set
 
 
 ### Error-prone practices
 
 * `A301`: Discouraged APIs
 * `A302`: Redefinition of built-in name
 * `A303`: Non-default source file encoding
