The test data has been edited to reflect RE2/Go differences:

• In a star of a possibly empty match like (a*)* matching x, the no match case runs the starred subexpression zero times, not once. This is consistent with (a*)* matching a, which runs the starred subexpression one time, not twice.
• The submatch choice is first match, not the POSIX rule.

Such changes are marked with 'RE2/Go'.

RE2 Test Files

re2-exhaustive.txt.bz2 and re2-search.txt are built by running 'make log' in the RE2 distribution https://github.com/google/re2/

The exhaustive file is compressed because it is huge.
