Ambiguous column names (not that kind)

Time for another quiz to impress your friends, if you have that kind of friends.

The manual page in question

mysql --skip-enable-disable-column-names=0 -e "select 1"
mysql --skip-disable-enable-column-names=0 -e "select 1"
mysql --loose-disable-enable-skip-column-names=0 -e "select 1"

What’s the result? An error about unknown options? A warning? Column headers enabled? Disabled?

mysql --skip-enable-disable-column-names=0 -e "select 1"

mysql --loose-disable-enable-skip-column-names=0 -e "select 1"
