The function exchanges point and mark.
When there is region, this also creates secondary.
When there is secondary, this converts secondary to primary in advance.

As a consequence, an user sees the function exchanges
 - `point' and `mark'
 - `point and mark' (= primary) and secondary
at the same time.
