 * Writes a failure to the CLI's error stream: as its message alone when the user's own declaration caused it,

 *
 * A stack records where nmr noticed a problem, which says nothing about the file a user has to edit; for nmr's
 * own fault it is where a report has to start. `describeError` covers an `Error` carrying no stack and a thrown
 * non-`Error` alike.
