CommentParsing

The comment parsing in dotc is used by both the comment cooking and the dottydoc tool.

The comment cooking is used to expand comments with <invalid inheritdoc annotation> and @define annotations. The rest of the comment is untouched and later handled by dottydoc.

def startsWithTag(str: String, start: Int, tag: String): Boolean
def tagIndex(str: String, p: Int => Boolean): List[(Int, Int)]

Produces a string index, which is a list of sections, i.e pairs of start/end positions of all tagged sections in the string. Every section starts with an at sign and extends to the next at sign, or to the end of the comment string, but excluding the final two characters which terminate the comment.

Also take usecases into account - they need to expand until the next usecase or the end of the string, as they might include other sections of their own
