This replaceActiveBlockParser()

replaceParagraphLines Int : replaceParagraphLines

withReplaceParagraphLines This withReplaceParagraphLines(Int lines)

Replace a number of lines from the current paragraph (as returned by MatchedBlockParser.paragraphLines) with the new block.

This is useful for parsing blocks that start with normal paragrapsh and only have special marker syntax in later lines, e.g. in this:

## Foo

The Foo line is initially parsed as a normal paragraph, then the === is parsed as a heading marker, replacing the 1 paragraph line before. The end result is a single Heading block.

Note that source spans from the replaced lines are automatically added to the new block.

Paramter lines indicates the number of lines to replace (at least 1); use Int.maxVal to replace the paragraph.
