Dept of second thoughts: keep aliasp_item in sync with tlistitem.
Commit d5b760ecb
wasn't quite right, on second thought: if the
caller didn't ask for column names then it would happily emit
more Vars than if the caller did ask for column names. This
is surely not a good idea. Advance the aliasp_item whether or
not we're preparing a colnames list.
