Subject: [PATCH] fix(links): peel a CJK label off a path glued behind it
 (#1053)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An agent reporting a file it wrote prints `原型:/tmp/a.html` or
`原型：/tmp/a.html` with no space. The label rule only accepted ASCII
labels behind an ASCII colon, so the whole token was read as a relative
path and the click reported it missing under the pane's directory.

Accept any alphabetic label, one character long when it is not ASCII,
behind either colon. A single ASCII letter stays a Windows drive.
