I think that’s fine; this is all guesswork anyway, and there are always
cases where we’ll get it wrong.  What’s useful though is tests to guard
against regressions in the heuristics.

Turns out that the failure in tests/channels.scm was a real bug:
‘channel-news-entry-commit’ was not resolving annotated tags correctly
(it would return the ID of the tag instead of the ID of the commit
pointed to by the tag).  Fixed in
778c1fb4eabbb48c05f6c7555c89466d5249ebce.

Applied!  I changed the second patch to preserve support for
non-annotated tags and to leave tests/channels.scm unchanged.

BTW, “git tag xyz” is not interactive AFAICS.

Thanks Sarah & Xinglu for this work!  Let’s update our packages!  :-)
