Re: search through alternative HISTFILE

Just for the record. I figured out that it is necessary to reset HISTNO 
to its old value after the search on accumulated history is done 
(otherwise the normal search will be confused):

function accumulated-history-incremental-search-backward () {
    fc -p $ACC_HISTFILE
    HISTNO=$(( $( wc -l < $ACC_HISTFILE ) + 1 ))
    zle history-incremental-search-backward
    fc -P
    HISTNO=$(( $( wc -l < $HISTFILE ) + 1 ))
}
