Module Name:    src
Committed By:   kre

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

Log Message:
Do a better job of reporting invalid numeric constants in arithmetic exprs.

For example, given $(( 08 + 1 )) (or similar) instead of reporting
"expecting end of expression"  - the generic error for parse failed,
which happened as this was parsed as $(( 0 8 + 1 )) because the 8
could not be a part of an octal constant, and that expr makes no sense -
instead say "unexpected '8' (out of range) in numeric constant: 08"
which makes the cause of the error more obvious.

NFC for valid expressions, just the error message (and the way the
error is detected).
