I'm getting sick of darcs using the wrong author because I set my DARCS_EMAIL.
I would like to have a file like .darcs/authors with one entry per line.
mail.com>

If I record a patch in a repo that does not have _darcs/prefs/author set,
instead of asking me what my email address is, I would like darcs to ask me to
make a multiple-choice selection, e.g.
 
 1. Eric Kow <E.Y.Kow@brighton.ac.uk>
 2. Eric Kow <kowey@darcs.net>
 3. Eric Kow <eric.kow@gmail.com>
 4. other...

Making Dan nosy on this because I think he wants something similar

The following patch updated issue issue1530 with status=resolved;resolvedin=2.8.0 HEAD

* Resolve issue1530: allow user to pick from multiple email address. 
Ignore-this: 531e6c9498f9155c1a8f926ee56a68e3
If your global authors pref has more than one line in it, Darcs will
prompt you something like:

  You have saved the following email addresses to your global settings:
  1. Fred Bloggs <fred@example.net>
  2. Fred Bloggs <fred@home.example.tld>
  3. BLOGGS Fred <fbloggs@example.com>
  4. Other
