I'm not quite sure what that is trying to achieve. I also can't
remember how I got it not to work in the first place because it
is now.

Interesting. If I was just planning to put the cursor at the end of
the line in all cases, it would probably be better. It is useful to
think about though because it would allow the resumption of the
search with the same string even if the line had been edited.

Okay, I'll probably put the push-line-or-edit in when enabled with
a style too then. Could we maybe agree a common prefix for the
contexts of the styles in Functions/Zle - ':zle:' maybe?

It is probably best to stick with zle .end-of-line in whatever
goes in Functions/Zle but I'm not sure that it is exactly what
I want to happen for the cursor position.

I'm currently experimenting with this:

  if (( HISTNO + 1 == ${(%%):-%h} )) && [[ $BUFFER[1,__savepos] != *$'\n'* ]]
  then
    CURSOR=__savepos
  elif [[ $RBUFFER != *$'\n'* ]]; then
    zle .end-of-line
  fi

as the cursor positioning and using:
  accept-line-and-savepos() {
    __savepos=$CURSOR
    zle .accept-line
  }
instead of accept-line (I probably also need to do others like
accept-line-and-down-history). On the way down, I'm not moving
the cursor at all. It's one of those things where I need to use
it for a while before I decide if it is a good idea or not but
let me know if you see any problems or if this sparks off any
other ideas.
