Re: Is there a delete-to-previous-slash key?

The easiest way is temporarily not to allow / to be part of a word and
use backward-delete-word:

backward-delete-to-slash () {
  zle .backward-delete-word
zle -N backward-delete-to-slash

but if you really want to delete anything else in the way you can
use something like:

backward-delete-to-slash() {
  integer pos=$CURSOR
  while (( pos > 1 )); do
    if [[ $LBUFFER[--pos] = / ]]; then
      return 0
  return 1
zle -N backward-delete-to-slash

That doesn't save it on the kill ring; I had hoped there would be some
shorthand for "delete this and put it on the kill ring" but the only ways I
can see are either to set the mark, or do it longhand with CUTBUFFER and
killring, and I couldn't be bothered.
