One of the effects is that |line-continuation| is always enabled.
! The original value of 'cpoptions' is restored at the end of the script, while
! flags added or removed in the script are also added to or removed from the
! original value to get the same effect. The order of flags may change.

and wants to know what it means. After months of studies the worlds
