Linking to a target with underscores did not work

For example, in a link like [MY_VALUE], the link would only try to resolve the text "MY" until the first underscore.
Since the markdown parser parses the link label as [TEXT:MY, EMPH:_, TEXT:VALUE], using the first TEXT child node
is not sufficient.
