Re: line continuation with sed

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

You might find something like this interesting:

show-trailing-space() {
  zle .$WIDGET &&
  if [[ $BUFFER = *(' '|$' \n'*)
        || $PREBUFFER = *$' \n'* ]]
  then POSTDISPLAY=$'\u21a9'
  else unset POSTDISPLAY
  fi
}
zle -N magic-space show-trailing-space
zle -N self-insert show-trailing-space
zle -N kill-whole-line show-trailing-space
zle -N kill-line show-trailing-space
zle -N kill-word show-trailing-space
zle -N backward-kill-word show-trailing-space
zle -N backward-delete-char show-trailing-space

Integrating this with other plugins etc. that may have rebound those
widgets or appropriated POSTDISPLAY is left as an exercise.  Other
improvements (bind to history motions etc.) are possible.
