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.
