Fix ALTER TABLE error message
This bogus error message was introduced in 2013 by commit f177cbfe676d,
because of misunderstanding the processCASbits() API; at the time, no
test cases were added that would be affected by this change. Only in
ca87c415e2fc was one added (along with a couple of typos), with an XXX
note that the error message was bogus. Fix the whole, add some test
cases.
Backpatch all the way back.
