[PATCH] Add signal for paste detection events

[irssibot]

• • • Issue [PATCH] Add signal for paste detection events #531 opened by @dgl

The attached patch adds two signals, "gui paste detected" and "gui paste flush" that allows a script to intercept certain paste events. It doesn't intercept the normal paste key (^K) but adds two more keys that scripts can use (^O and ^P).

It currently hardcodes the keys that are allowed, I don't like that much but I can't think of a nice way to make it configurable. (I guess a perl function to register interest, but that seems like a huge amount of effort for something so simple.)

I've written a script to use this, you can find it at http://dgl.cx/irssi/pastie.pl

It would be nice to see this in Irssi core, as I think the script could be quite useful.
