Can you please show some examples?  First, what text triggers the new
functionality correctly, when the user types a password at some
relevant prompt, and then what happens when an unrelated prompt is
taken by the filter function as a prompt for a password.  I'd like to
understand better what happens in each case.

Sorry, this doesn't really tell me enough, because I don't think I
understand the relevance of dumb shells and comint to the issue at
hand.

Thanks.
