 *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.
