Function yaml_parser_split_stem_comment

parserc.go:786–804

Split stem comment from head comment. When a sequence or map is found under a sequence entry, the former head comment is assigned to the underlying sequence or map as a whole, not the individual sequence or map entry as would be expected otherwise. To handle this case the previous head comment is m
