Module Name:    src
Committed By:   christos

        src/bin/sh: parser.c

Log Message:
PR bin/51027 - fix the parsing of references to shell parameters
when given without braces (ie: $2 etc).  Only the first 9 shell
parameters ($1 .. $9) and the special parameter ($0) can be
referenced this way, $10 is ${1}0 not ${10}.   Make it so.
This bug brought to notice by Sven Mascheck's web pages which
discuss (among other things) the history of this (and other ash
based) shells .. see http://www.in-ulm.de/~mascheck/ (from kre@)
