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.
