I don't know the history of the testcase, and this is only my own
opinion, but I tend to agree with you.   I think we should keep one
test with \t, to make sure that a tab does trigger the completion,
but the rest of the testcase should be using the "complete" command.
That's what we do at AdaCore anyways...
