Please make sure your first paragraph of the log message start with
a full sentence, not an incomplete tail part of a sentence as if the

The output is wrong in that 22ffc39 is v1.7.2-336-g22ffc39, not 104.
Putting an arbitrary number that can change depending on how the
traversal went will close the door to possible follow-up work on the
recent sha1-name-more series (0958a24^2, most importantly aa1dec9e)
to prolong the shelf-life of describe output by filtering candidate
commits with reachability from the tag and the number of commits
from the tag.
In any case, it is not clear to me if this is a useful example to
help readers of this commit to understand why this new feature is
useful. 22ffc39 was created to mark that the work done for 1.7.2.x
maintenance track back then were all contained in the 'master' by
merging 'maint' when it was pointing at v220.127.116.11. Saying the commit
is newer than v18.104.22.168 gives more information than it is newer than
v1.7.2, as by convention v1.7.2 must be older than v22.214.171.124, no?
