This could be confusing not only for novices; in either case, no range
should be insinuated by describe_detached_head.
We actually do not insinuate any range in these output. These dots
denote "truncated at the end, instead of giving full length."
Another place these "many dots" appear is "git diff --raw", for
example.
<bikeshed> The fancy word for the three dots is an `ellipsis`
- the omission from speech or writing of a word or words that are
superfluous or able to be understood from contextual clues.
- from the Ancient Greek: ἔλλειψις, élleipsis, "omission" or "falling
short".
The user/reader confusion may still be there though.
