I really like the intent of this patch, but I actually find the new
message even more confusing.

Is this a time when we could use hint() to give a multi-line explanation
(and probably a matching advice.* config)? Like:

  hint: If the --author parameter contains angle brackets ("<>"), it
  hint: is treated as a literal name/email pair to use. If not, then
  hint: the history is searched for an existing matching author.

or something?
