Not easily.
With an ordinary motion widget, you can write a wrapper that grabs the
value of HISTNO and puts it somewhere useful. Simple example:
up-line-or-history() {
zle .up-line-or-history "$@"
RPS1=$HISTNO
zle reset-prompt
zle -R
}
zle -N up-line-or-history
With history-incremental-search-*, you don't have this luxury, because
the input and display for the incremental pattern is handled entirely
inside the widget; there is no hook for resetting the prompt.
If you're feeling ambitious, Functions/Zle/history-pattern-search is a
good starting point; it's already manipulating HISTNO so it shouldn't
be hard to find a place to add a few lines to poke something into the
prompt.
