Finally we need to know if the `code_node` was recognised by being
indented or not. If it was, the client of this data will want to
-strip of the leading tab or 4 spaces. Hence a `needs_strip` flag is

+strip off the leading tab or 4 spaces. Hence a `needs_strip` flag is
+needed. This will be set to 8 if a tab is found and 4 if four spaces are found.
+This means the relative indent of text in the node

+The relative indent is needed for detecting indents in the overall file.
