#autoload
# Usage:
# _combination [-s SEP] VARIABLE KEYi=PATi KEYj=PATj ... KEYm=PATm KEY EXPL...
#
# VARIABLE must be formd as PREFIX_KEY1_..._KEYn.
#
# Example: telnet
#
# Assume an user sets the variable `telnet_hosts_ports_users' as:
#
# telnet_hosts_ports_users=(
# host0:: host1::user1 host2::user2
# mail-server:{smtp,pop3}:
# news-server:nntp:
# proxy-server:8000:
# )
#
# `_telnet completes' hosts as:
#
# _combination telnet_hosts_ports_users \
# ${options[-l]:+users=${options[-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 telnet_hosts_ports_users \
# ${options[-l]:+users=${options[-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 telnet_hosts_ports_users \
# ${line[2]:+hosts="${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.
