The COBOL parser doesn't make a comment green if there is a character just before the star (*).
In my environment, we put tags everywhere, and most of them have 6 characters, so most of the COBOL comments are not correctly parsed in the text editor, and this creates a big confusion sometimes.
It is perfectly valid to have a tag of 6 characters and a star (*) just after that, and that should be parsed as a comment.
This appears to be a duplicate of [#1893].
