Subject: 25.3; authinfo password backslash problem
Date: Wed, 16 May 2018 17:56:01 +0100

Assumption: 
  User's IMAP password has a backslash character ('\') in it.

Steps:
  1. Setup gnus so it connects to an imap backend
  2. Start gnus
  3. Enter the username and password of the IMAP account
  4. Say yes to saving the credentials in .authinfo
  5. Quit emacs
  6. Restart emacs
  7. M-x gnus
  8. Authentication fails

The password saved in the .authinfo file has its backlash escaped
('\\').  If the file is edited directly and the extra backslash is removed,
authentication works again.
