CVS commit: src/bin/sh

Module Name:    src
Committed By:   kre
Date:           Mon Mar 20 11:31:00 UTC 2017

Modified Files:
        src/bin/sh: arith_token.c

Log Message:
Alternative way of writing (part of) the arithmetic lexical analyzer
- committed separately to make it easier to swap back if desired.

This version avoids open coding is_name() and isdigit() - measurements
show it is perhaps fractionally faster (though the difference is so small
as to probably be statistically insignifigant - if I were a statician
I might understand that) and just a little larger than the previous version.
