[PATCH 0/4] send-email: correct various issues

Junio, these are technically all independent bug fixes, but they were minor, so I've lumped them together. I figured you'd just add them to the js/send-email topic anyway. Also, I apologize for causing trouble in master. :-(

Björn, I've cc'd you for 3/4, which caused me to notice the problem that led to 4/4. Uwe, I've cc'd you for 4/4.

Jay Soffian (4):
  send-email: don't attempt to prompt if tty is closed
  send-email: ask_default should apply to all emails, not just the
    first
  send-email: correct two tests which were going interactive
  send-email: ensure quoted addresses are rfc2047 encoded
