linkify-it only recognizes ASCII characters as URL boundaries. In Chinese
or Japanese text a URL followed by "。" (or any other full-width
punctuation) was greedily swallowed into the URL along with everything up
to the next whitespace, producing hrefs like
`https://.../pull/1623。merge` that 404 when clicked.
Truncate the detected URL at the first CJK full-width punctuation
character and re-scan the tail, so adjacent URLs separated only by
full-width punctuation are still each linked individually. The
terminator character set mirrors the fix applied in mattermost/marked#22.
