Hi all,
I backported the trunk parser changes and applied the Ragel fix to
branches/stable_1-2 . Two tests are currently failing... could someone
(Eric, Ry?) take a look at these? I am not good enough with Ragel to
be able to say whether or not the eof change is related to the test
failures.
Thanks,
Evan
