[pmwiki-users] Markup() with _?

[Thomas -Balu- Walter]

I'm a little over-worked at the moment, so I might just not see the
reason. Just point me somewhere if it is this way.

I am trying to add a new Markup like
Markup('somemarkup', 'inline', '/&some_markup;/', 'some replacement');

However it seems that having an underscore does not work there?
Everything works fine, if I remove the "_".
