Overview

This cop checks that comment annotation keywords are written according to guidelines.

NOTE: With a multiline comment block (where each line is only a comment), only the first line will be able to register an offense, even if an annotation keyword starts another line. This is done to prevent incorrect registering of keywords (eg. `review`) inside a paragraph as an annotation.

Examples:

# bad
# TODO make better

# good
# TODO: make better

# bad
# TODO:make better

# good
# TODO: make better

# bad
# fixme: does not work

# good
# FIXME: does not work

# bad
# Optimize does not work

# good
# OPTIMIZE: does not work
