9The test data has been edited to reflect RE2/Go differences:
10  * In a star of a possibly empty match like (a*)* matching x,
11    the no match case runs the starred subexpression zero times,
12    not once.  This is consistent with (a*)* matching a, which
13    runs the starred subexpression one time, not twice.
14  * The submatch choice is first match, not the POSIX rule.

16Such changes are marked with 'RE2/Go'.
