I looked through the user's manual but there didn't seem to be a very
good place to do this.  And, this isn't a variable but a constant,
since I think it doesn't make sense to let the user customize it.  So
I'm hoping you will agree that it is ok to leave it as-is.

Here's a new patch that does document the new constant in the
reference manual.  It also omits the ERC part of the patch since
Michael has that in hand.

Comments?
