I'm hoping Bandali and other ERC users will look, also.  I spoke to
someone on ERC today who is using the (prior version), I believe and
has agreed to mention any issues or suggestions.  (They agreed with
you about e-l-d-f-c being irrelevant, which seems pretty darned
obvious to me now too.)

*Smacking of forehead*  Right you are.

I'm pulling master now.  This version was created after evaling your
suggested one-liner in my erc.el buffer & please let me know if that's
got it.

Again, thanks
