RPL_WHOREPLY messages generated by IRC_WHO don't include flags (*,@,+)
that should appear according to this description:
http://www.mishscript.de/reference/rawhelp3.htm#raw352
Other IRC servers do include the flags.
Modify who-test.e to expose missing flags,
modify ngircd-test.conf to accommodate who-test.e, and fix
irc-info.c to correct these problems.
Dana Dahlstrom reported that IRC_WHO did not follow
RFC 2812, Section 3.6.1. Specifically:
- IRC_WHO did not send "G" flag instead if "H" if client was away
- did not search username/servername/hostname etc. if argument
was not a channel.
Fix all of the above and tidy things up a bit.
Also add IRC_WHO test script contributed by Dana.
