Make Matrix or Telegram gateway users to look like IRC users in irssi

Instead of

12:35 < mx> <Michael> tehdäänpä sit näin :)

you will get

12:35 < Michael> tehdäänpä sit näin :)

This script also handles joins and parts as when people join and leave the channel. It makes the people visible on that channel for easy tab-completion of the nicks.

Place detelexify.pl under ~/.irssi/scripts/autorun/ on your irssi server. Edit the script by adding your Matrix / Telegram gateway idents to the array %telex_nicks. Then run the script in irssi:

/run ~/.irssi/scripts/autorun/detelexify.pl

Enjoy!

The script currently has no channel and network limits for the Telegram gateway bots. They can act as any user on the channels they are joined into. #3

The nicks joined into that channel are not present in your IRC network in real. Therefore you need to be careful when sending private messages to those nicks. The messages will be received by someone else if there's such nickname in the same network. #4

There is no way to distinguish the person if they is joined the channel via Matrix and real IRC. That's the idea of this script, the same nickname may be used on both networks and it produces no nickname pollution if you are using both networks.

Please submit a patch if you fix any of these issues
