function arg list didn't match the method arglist, which made for
confusing function help.

Reported by Barry Fishman <barry@ecubist.org>.
Along the way, I checked other variables which are similarly let-bound
to nil and then read with any intervening assignment, which found
another similar case of missing `defvar`s plus a bit of dead code.

Remove constant nil var `beg`.
