Bug#834853: exim4-config: update-exim4.conf does NOT update ANYTHING

[Bob Goldberg]

Package: exim4-config
Version: 4.80-7+deb7u3
Severity: important
Tags: upstream

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
needed to update exim4 to shut off "purging envronment" warning
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
after changing conf files, ran update-exim4.conf
   * What was the outcome of this action?
discovered that running the update does NOT UPDATE A SINGLE THING.
discovered that update script EXPRESSLY checks for existence of
/etc/exim4/exim4.conf and IF /var/lib/exim4/config.autogenerated is
EQUAL TO ITSELF!!!!!???  THEN EXIT - un-ceremoniously.
man page and docs for this script say NOTHING about specifying -o
   * What outcome did you expect instead?
I expected the update script to update the xim4 configuration environment!

*** End of the template - remove these lines ***
