#autoload
# options:
#
# -n plugin - can complete nicknames from specified plugin
# -s sep    - complete a list of addresses separated by specified character
# -c        - e-mail address must be of form user@host (no comments or aliases)
#
# Plugins are written as separate functions with names starting `_email-'.
# They should either do their own completion or return the addresses in the
# reply array in the form 'alias:address' and return 300. The -c option is
# passed on to plugins (and -n could be if needed ever). New plugins will be
# picked up and run automatically.
