Fix searching YAML/TOML delimiters in frontmatter

When a YAML/TOML's delimiter character sequence is included in a
frontmatter string, parser mistakes it as a delimiter. This fixes it by
checking a character right before the delimiter sequence is '\n' or it
is the beginning of the frontmatter.

Fix #1320
