Re: some way to inherit kill ring in su'd shell?

[Greg Klanderman <gak@xxxxxxxxxxxxxx>]

Hi Bart,

With the patch below, preserving just the CUTBUFFER is this simple:

function zle-line-init () {
  if [[ ${ZLEKILLRINGPID-} != $$ && -n ${ZLECUTBUFFER-} ]] ; then
    CUTBUFFER="$ZLECUTBUFFER"
  fi
}
zle -N zle-line-init

function zle-line-finished () {
  export ZLEKILLRINGPID=$$ ZLECUTBUFFER="$CUTBUFFER"
}
zle -N zle-line-finished

Is an enhancement something like this acceptable?

thanks,
Greg
