Support underscores in content type keys

Using the Inclusion mode (haven't tested with Exclusion mode), I need to add two lines for each Content Type that has a multi-word name:

To include FCKEditor when I'm adding a new node of "content-type" I need to place hyphens between the words in the Include box:
content-type@*.edit-body
To include FCKEditor when I later edit a node of "content-type" I need to place underscores between the words in the Include box:
content_type@*.edit-body

Is this intentional?

Per the note on "Type" at admin/content/types/add: when defining the content type, underscores are used which are changed to hyphens when the create content URL is created.

Thanks.
