I'm not sure at which point this might have shown up -- possibly
after workers/38991 (commit f026a4dc) -- but I think it has to be
considered a bugfix, because _zsh_highlight_call_widget (or in the

Of course in this case you'd really like to know what's happening at
the time the prompt is displayed; %N is really intended for use in PS4
where the recalculation and the display occur together.  For PS1 that
only happens when the editor starts up for each new command input.

In what circumstances would you expect to need %N in PS1?  That is,
the reason to use any %-expando is to display information that will
change after the prompt is assigned.  If there is no case in which
you would expect %N to return something different, then you should
not need to use it.  Instead for example:

    PS1="$ZSH_ARGZERO:t %# "
