[PATCH 21/25] emacs: Cleaner interface when prompting for sender address

Subject: [PATCH 21/25] emacs: Cleaner interface when prompting for sender address

Most of the time, every entry in the list of identities has the same user name
part. It can then be filled in automatically, and the user can only be prompted
for the email address, which makes the interface much cleaner.
