This has unpleasant results when the point is not immediately after
the ERC prompt, and likely in other cases I haven't found.

For a next pass I plan to:
* use `erc-display-line' instead of `insert'
* remove the new binding while we discuss ideal approaches
* create from master and see if I can I get tabs/spaces correct
* CC emacs-erc in hopes of soliciting more inputs

Thanks to Amin and others for discussions on IRC this evening.
