# Restrict the start of the editable line to the region between cursor
# and mark (including the character at the end).  Can be bound used as
# a zle widget, or called as a function from another widget.
#
# Optionally accepts exactly two arguments, which are used instead of
# $CURSOR and $MARK as limits to the range.
#
# Upon exit, $MARK is always the start of the edited range and $CURSOR
# the end of the range, even if they began in the opposite order.
#
# Other options:
#   -p pretext   show "pretext" instead of the buffer text before the region.
#   -P posttext  show "posttext" instead of the buffer text after the region.
#                Either or both may be empty.
#   -n           Only replace the text before or after the region with
#                the -p or -P options if the text was not empty.
#   -l lbufvar   $lbufvar is assigned the value of $LBUFFER and
#   -r rbufvar   $rbufvar is assigned the value of $RBUFFER
#                from any recursive edit (i.e. not with -S or -R).  Neither
#                lbufvar nor rbufvar may begin with the prefix "_ntr_".
#   -S statevar
#   -R statevar
#      Save or restore the state in/from the parameter named statevar.  In
#      either case no recursive editing takes place; this will typically be
#      done within the calling function between calls with -S and -R.  The
#      statevar may not begin with the prefix "_ntr_" which is reserved for
#      parameters within narrow-to-region.

# set the minimum of options to avoid changing behaviour away from
# user preferences from within recursive-edit
