The sorting is possibly a bit of a hack.
This lets you make wrappers that use set-local-history without changing
the global setting, or show the current setting in the prompt, or
whatever.
function _set_local_history() {
local oldstate=$ZLE_STATE
zle .set-local-history
if [[ $ZLE_STATE == $oldstate ]]; then
return
fi
if [[ $ZLE_STATE == *globalhistory* ]]; then
psvar[8]=(1)
else
psvar[8]=()
fi
zle reset-prompt
}
zle -N set-local-history _set_local_history
function _local_history_command {
if [[ $ZLE_STATE == *localhistory* ]]; then
zle ${WIDGET#local-}
return
fi
zle .set-local-history -n 1
zle ${WIDGET#local-}
zle .set-local-history -n 0
}
zle -N local-down-history _local_history_command
zle -N local-up-history _local_history_command
bindkey '^X^P' local-up-history

Of course I managed to invert this test.

I got a build failure on install.info:
tzsh.texi:15164: @item found outside of an insertion block.

Thanks, when I added it I didn't look to carefully and just assumed
the enditem() was paired with the item() for each entry.
