Blank lines in USAGE produce unwanted behavior with !help

[evstar3]

Overview

Calling !help on a module with a blank line in its USAGE produces unwanted behavior.

Okay, why?

When !help is called, Bobbit produces a message with message.copy() for each line in USAGE. When there is a blank line in USAGE, one of these calls will be message.copy(body=''). In the copy method, the body evaluates to false and the original body of the !help command is copied. Because message.copy() also copies the nick, Bobbit sees this message as a command invocation and replies to it.
