Documentation
Determines whether new frames are always created.
Non-nil means only create a frame for undisplayed buffers. Nil
means always create a new frame. Regardless of its value, ERC
ignores this option unless erc-join-buffer is frame. And
like most options in the erc-buffer customize group, this has
no effect on server buffers while reconnecting because ERC always
buries those.
