Subject: bug#39345: 28.0.50; rcirc-authenticate-before-join due to case sensitive mismatch
Date: Wed, 29 Jan 2020 09:29:26 -0500

1. join irc.freenode.net with a lowercase nick "examplenick"
2. authenticate to nickserv
3. nickserv echos back  "-NickServ- You are now identified for
"Examplenick" capitalizing the nickname.
4. rcirc-authenticate-before-join does not trigger, so no channels are
auto-joined.

The existing check is case sensitive.  The patch below fixes the issue
for me on freenode.
