That may mean there is room for improvement in split_ident_line to
be more resilient in removing cruft. With something like:

  Name <email@host>-<> 123456789 -0000

it would obviously be nice to find the date timestamp there, but I
wonder what the "email" field should return? The full broken string, or
just "email@host"? One way is convenient for overlooking problems in
broken commits, but I would worry about code paths that are using
split_ident_line to verify the quality of the string (like
determine_author_info). It's possible we would need a strict and a
forgiving mode.
