Error in plone.recipe.squid 1.0b1 options

The documentation for plone.recipe.squid 1.0b1 at http://pypi.python.org/pypi/plone.recipe.squid/1.0b1 describes "Squid-specific Configuration Options":

default-hostname
visible-hostname
visible-email

In fact, the code appears to look for names with underscores:

self.options.get("default_hostname", None)
self.options.get("visible_hostname", None)
self.options.get("visible_email", '')

Obviously this could be fixed by changing either the docs or the code. To be consistent with other options, though, dashes are preferred.
