New Revision: 121019

URL: http://llvm.org/viewvc/llvm-project?rev=121019&view=rev
Log:
Add two test cases to exercise many expression commands:
    o test_many_expr_commands()
    o test_expr_commands_can_handle_quotes()

Mark test_expr_commands_can_handle_quotes()
as @expectedFailure:

    # rdar://problem/8686536
    # CommandInterpreter::HandleCommand is stripping \'s from input for WantsRawCommand commands
