Collect every nest(<predicate-with-path>, ...) block in the
router code along with the path prefix it carries and the
byte range of its parenthesised argument list. Returns
[{start_byte, end_byte, prefix}, ...]. Inner verb calls
whose match position falls inside [start, end) should have
prefix prepended.
