In 'failure scenario', I admire that it maybe a rare case, the problem is that
tag itself doesn't have information whether pre-release or official release.
(need to contains the identifier to distingish)

Thus, suggested watch rule works in most cases if upstream tagged as pre-release to
 v0.1.97pre or something,
but it will not work as expectedlly if v0.1.97 tag is given to pre-release.
(it is bad practice, though)

In GitHub, pre-release requires tag, so it may happen re-creating same tag for release
from a sysytem point of view.


Anyway, it may be a trivial exceptional case, so I'll close it.
