#
# Usage: /cgrep <regexp>
#
# Shows all WHO records matching that regexp in a friendly yet complete format
# Works on the active channel only
#
# This is a bit like c0ffee's ls command, except it matches ALL returned data.
# Since IRSSI doe snot cache realnames properly, this script calls WHO once
# and awaits the results.
#
# Also check out 'joininfo.pl' which shows lots of WHOIS info when a person
# joins the channel.
#
# FORMAT SETTINGS:
# cgrep_match Matching record
# cgrep_line Start and end line format
#
