Changes in channel_connect_to

[rapier]

I just want to make sure I'm interpreting this correctly.

In 5.0 channel_connect_to would only return the requested socket. You'd 
then need to use this socket to create the channel with with channel_new.

In 5.1 channel_connect_to doesn't return the socket but rolls in 
channel_new and now returns the channel directly. The usage of 
channel_new hasn't changed though, only channel_connect_to.

Is that about right? Are the any subtleties I'm missing?
