Don't use underscore for emphasis around function containing underscores.
Don't use underscore for emphasis around function containing underscores.

Obviously, it is not possible for textile to detect function names containing
underscore characters and ignore them in a '_(highlight) ... _' environment,
even when they're surrounded by '+' marks (which introduces a bunch of other
markup groups). Instead, use direct CSS markup.
