*SUMMARY: Testing numeric literals that begin with 0. 
*This test arose from Bugzilla bug 49233.
*The best explanation is from jsscan.c:                
*
*     "We permit 08 and 09 as decimal numbers, which makes 
*     our behaviour a superset of the ECMA numeric grammar.  
*     We might not always be so permissive, so we warn about it."
*
*Thus an expression 010 will evaluate, as always, as an octal (to 8).
*However, 018 will evaluate as a decimal, to 18. Even though the
*user began the expression as an octal, he later used a non-octal
*digit. We forgive this and assume he intended a decimal. If the
*JavaScript "strict" option is set though, we will give a warning.
