I think this line is the culprit.  AmS-TeX is detected by something
matching the regex "\\\\document\\b" near the beginning of the document
(see `TeX-format-list').

I don't know AmS-TeX at all but I think the regexes in `TeX-format-list'
should be matched case-sensitively (they are currently not), no?  And
then your \Document wouldn't be matched.

I guess we should use amstex -output-format=pdf then, right?
