Trying to be clever by filtering commented lines inside
`getNextEmbedBlock()` does not work as expected. The `#` may as well be
part of a multi-line quoted string where it must not be treated as the
beginning of a comment. Thus, we only must ensure that a comment-like
line does not skip the process of getting the next line of the embed
block.
