Subject:   * Add choice of Authorization flow to Alpine. Alpine supports two
 ways to get     authorization to read email. One is called "Authorize" and
 the other "Device".     Some servers support both, some only one. For servers
 that support both, Alpine     will ask if it does not know which method to
 choose. Inspired by a conversation     with Pieter Jacques.
