This is not an RFC any more, but a serious series. Occasionally a user is given an object hash from a blob as an error message or other output (e.g. [1]).
It would be useful to get a further description of such a blob, such as the (commit, path) tuple where this blob was introduced. This implements the answer in builtin/describe, however the heuristics are weak. See patch 6 for details.
