Sorry, I had forgotten about this.

I think the best to use is perhaps Martin Ebourne's from 16011. It is
as follows though I've modified it slightly so that it will do a down
line if we are back at the end of the history and so that you can force
a down history with a numeric argument. Does anyone think it is worth
it to incorporate Dominik Vogt's changes in users/4712 which basically
just account for lines containing only spaces and tabs?

In the function I use, I also have:

  elif [[ -n $PREBUFFER ]]; then
    zle .push-line-or-edit

in the middle of the up-line function (unfortuately adding an
up-line-or-history after push-line-or-edit doesn't seem to work). I
expect most users wouldn't expect this so I'll leave it out.

I was also hoping to move the cursor to the end of the line after
searches but I can't see how I can move it back before the next search
without using the mark. I was hoping someone else would answer the
question in users/4735 because I don't know the answer myself and
suspect it can't be done.

So, are there any objections if I commit the following instead? Peter's
documentation looks to still be entirely applicable.

up-line-or-beginning-search() {
  if [[ $LBUFFER == *$'\n'* ]]; then
    zle .up-line-or-history
    __searching=''
  else
    zle .history-beginning-search-backward
    __searching=$WIDGET
  fi
}

down-line-or-beginning-search() {
  if [[ $LASTWIDGET = $__searching || $NUMERIC -gt 0 ]] &&
      zle .history-beginning-search-forward; then
    __searching=$WIDGET
  elif [[ $RBUFFER == *$'\n'* ]]; then
    __searching=''
    zle .down-line-or-history
  else
    __searching=$WIDGET
    zle .history-beginning-search-forward
  fi
}
