Overview

Checks for redundant message arguments to `#add_offense`. This method will automatically use `#message` or `MSG` (in that order of priority) if they are defined.

Examples:


# bad
add_offense(node, message: MSG)
add_offense(node, message: message)
add_offense(node, message: message(node))

# good
add_offense(node)
add_offense(node, message: CUSTOM_MSG)
add_offense(node, message: message(other_node))
