Thanks Mikael. If it is not in the buffer I do not care.
But I cannot work your example.

Found this below in a config file somewhere and thought I could
adapt it.  I want to exclude all commands that have "foobar"
anywhere in them, as the command or in the arg list.
Quick hack did not work.  All lines are still written to
the history file.

zshaddhistory() {
    local line=${1%%$'\n'}
    local cmd=${line%% *}

    [[ ${#line} -ge 5
        && ${cmd} != "rm"
        && ${cmd} != (l|l[sal])
        && ${cmd} != (c|cd)
        && ${cmd} != (m|man)
        && ${arg} != (*foobar*)
    ]]
}
