Re: zle kill-region without mark consider start of line as mark

[Mikael Magnusson <mikachu@xxxxxxxxx>]

       REGION_ACTIVE (integer)
              Indicates if the region is currently active.  It can be
assigned 0  or
              1  to  deactivate  and  activate the region
respectively. A value of 2
              activates the region in  line-wise  mode  with  the
highlighted  text
              extending for whole lines only; see Character Highlighting below.
