# Usage:
# _combination [-s S] TAG STYLE \
# Ki1[:Ni1]=Pi1 Ki2[:Ni2]=Pi2 ... Kim[:Nim]=Pim Kj[:Nj] EXPL...
#
# STYLE should be of the form K1-K2-...-Kn.
#
# Example: telnet
#
# Assume a user sets the style `users-hosts-ports' as for the my-accounts
# tag:
#
# zstyle ':completion:*:*:telnet:*:my-accounts' users-hosts-ports \
# @host0: user1@host1: user2@host2:
# @mail-server:{smtp,pop3}
# @news-server:nntp
# @proxy-server:8000
#
#
# `_telnet' completes hosts as:
#
# _combination my-accounts users-hosts-ports \
# ${opt_args[-l]:+users=${opt_args[-l]:q}} \
# hosts "$expl[@]"
#
# This completes `host1', `host2', `mail-server', `news-server' and
# `proxy-server' according to the user given with `-l' if it is exists.
# And if it is failed, `_hosts' is called.
#
# `_telnet' completes ports as:
#
# _combination my-accounts users-hosts-ports \
# ${opt_args[-l]:+users=${opt_args[-l]:q}} \
# hosts="${line[2]:q}" \
# ports "$expl[@]"
#
# This completes `smtp', `pop3', `nntp' and `8000' according to the
# host argument --- $line[2] and the user option argument if it is
# exists. And if it is failed, `_ports' is called.
#
# `_telnet' completes users for an argument of option `-l' as:
#
# _combination my-accounts users-hosts-ports \
# ${line[2]:+hosts="${line[2]:q}"} \
# ${line[3]:+ports="${line[3]:q}"} \
# users "$expl[@]"
#
# This completes `user1' and `user2' according to the host argument and
# the port argument if they are exist. And if it is failed, `_users' is
# called.
