With the updated patch, when I select "EWS URL OAuth 2.0 settings 
(no autodiscovery)", all the widgets are disabled.  The blank 
values are no longer added though.  However, if I then set the 
value, without configuring anything, excorporate-configuration 
stays nil.  So I don't think the patch is correct yet.
