Reading the spec of Commonmark, I noticed the following:
HTML: Compare 4.6 and 6.8, specifically, the list of tags in 4.8 and this statement:
>that looks like an HTML tag is parsed as a raw HTML tag and will be rendered in HTML without escaping.
Links: In the second definition of links destination:
anonempty sequence of characters that does not include ASCII space or control characters, and includes parentheses only if (a) they are backslash-escaped or (b) they are part of a balanced pair of unescaped parentheses that is not itself inside a balanced pair of unescaped paretheses.
Does this mean that link destinations can be without parenthesis?
P. S.: Is this issue with blockquotes a bug or am I doing something wrong?
