From fe42762f236e23fefe47e67b6c248507d0ac5c8a Mon Sep 17 00:00:00 2001
From: Guy Harris <guy@alum.mit.edu>

Subject: Move some more stuff into wsutil.

Move the routines to parse numerical command-line arguments there.

Make cmdarg_err() and cmdarg_err_cont() routines in wsutil that just
call routines specified by a call to cmdarg_err_init(), and have
programs supply the appropriate routines to it.
