[Lldb-commits] [PATCH] new lldb-mi token test and cleanup

[dawn at burble.org]

Hi Abid,

I see you committed the patch but the new test case TestMiSyntax.py
didn't get added somehow - not sure what happened.  Please try again?

I've attached a new patch which adds just that test case for your
convenience.  Your commit message for the new test case is:

    test_lldbmi_tokens: Add test for MI tokens.

Thanks,
-Dawn
