Eclipse plugin parser should be consistent with Core parser with regards to comments

The story editor (Eclipse plugin) displays a line starting with "Unable to render embedded object: File (--" as a comment line, painting it green. It does not require a space after ") not found.--". It is the same with some other keywords in the story editor, for example I can start a line with Scenario:blabla and the story editor recognizes it as a scenario.

But the story parser of jbehave-core requires a space after a keyword like "!--". So it does not fit toghether. The story parser of jbehave-core and the one of the Eclipse plugin should parse the story in the same way. Otherwise it is misleading what the story editor displays.

Besides that, usually comment keywords don't include a space (XML, SQL, Javadoc etc.) So it is contra intuitive in a way. But I don't know how logical it would be to make an exception just for the comment keyword but not for "Given", "Scenario" and so on. Maybe a space should be optional for all story keywords.
