There are a couple of things in lurc where the code was lifted right out of
later versions of X-Chat - to keep things simple, I'm writing down where
what came from, so I can give proper attribution.

All of the base code is from xchat 1.0.0; very little has been done to
change it.

/ignore command and ignore menu:
Backported from xchat 1.2.0, modified slightly to suit my needs.

handle_multiline \n \r filter:
Backported from xchat 2.4.4, modified slightly to allow multiline pastes
with commands in them to not have those commands run, but the basic
filtering is exactly the same code.

Fix for new tabs to front bug:
Backported from xchat 1.2.0, no changes.

Fix for logging which previously produced ^O charachters from xchat 1.8.11

Fix for logging channels with / in the name from xchat 1.8.11

Backport for too much text on a line handling from xchat 1.8.11, 2.4.4 and
2.6.6.

Long file name with spaces dcc send bugfix backported from xchat 1.8.11

feature for server messages go to their own tab/window backported from xchat
1.2.1
