Excrescent final t

Local community radio station is doing a whole set of holiday-themed 'don't drink and drive' tunes. (Yah hey, it's Wisconsin.) They just played Asleep at the Wheels' deeply moving "Christmas in Jail" and as they sang "I wished I was dead", I realized that the context didn't allow a past reading, and things like 'makes me wished I was dead' are thoroughly possible for many speakers. So, this is another one of those excrescent final -t cases, like once, twice, else, across which are realized [wʊnst], [twa:st], [ɛwst], [əkrawst], all from the Dictionary of American Regional English.

This is the counterpoint to a current discussion over on ads-l about use to and suppose to.
