Here it is.

  [1/7]: ident: refactor empty ident error message

This one is only tangentially related. I was going to touch the message
more in patch 3, but decided not to (details in that patch).

  [2/7]: ident: refactor NO_DATE flag in fmt_ident
  [3/7]: ident: let callers omit name with fmt_indent
  [4/7]: format-patch: use GIT_COMMITTER_EMAIL in message ids

These ones should fix Michael's failing test and restore the original
behavior.

  [5/7]: ident: rename IDENT_ERROR_ON_NO_NAME to IDENT_STRICT
  [6/7]: ident: reject bogus email addresses with IDENT_STRICT
  [7/7]: format-patch: do not use bogus email addresses in message ids

These ones prevent bogus message ids from being generated at all
(which is an improvement over the previous state).
