Documentation
Regex pattern for a colon-enclosed group of tags.
The regexp does not match encosing spaces and tabs, e.g.,
":TAG1:TAG2:". Match group 1 stores the tags with the enclosing
colons, and match group 2 stores the tags without the enclosing
colons. Built using org-tag--valid-char-set with the addition of the
colon.
