[Bro-Dev] [JIRA] (BIT-1324) default_path_func does weird things to underscores

[Justin Azoff (JIRA)]

Justin Azoff commented on BIT-1324:
-----------------------------------

Ran into the issue using https://github.com/set-element/misc-scripts/blob/master/wordpress.bro  which ends up creating a wp__p_arse.log

It should probably be module Wordpress, but it is still odd behaviour.
