  Log Message:
  -----------
  imap: Finish all commands before starting IDLE.

We don't want to send tagged command replies only after the DONE. Also this
fixes assert-crash:

Panic: file imap-client.c: line 852 (client_check_command_hangs): assertion
failed: (!have_wait_unfinished || unfinished_count > 0)

Which could be reproduced by:

printf "0 SELECT INBOX\n1 NOOP\n2 IDLE\n"; read; printf "DONE\n"; read) | ./imap
