Any fish equivalent to zsh's SHARE_HISTORY?

Hi all,

Subject says it all: 

> SHARE_HISTORY <K>
> This option both imports new commands from the history file, and also causes your typed commands to be
appended to the history file (the latter is like specifying INC_APPEND_HISTORY)

I'm new to fish and really hope there's an equivalent? 

cheers, Fabian

there shoudln't be any need. history is shared across all running
shells, thus you never need to import from or export to the history file
in order to share history with other shells, because it efectively
happens automatically every time you run a command. (the command is
added to the history file and imported to the history of all other
running shells.

greetings, martin.

Thanks, Martin! Unfortunately this is not what I'm seeing. I used the OS X installer from
http://ridiculousfish.com/shell/beta.html. It looks to me as if there's a delay before any commands
are appended. Which would match my understanding of https://github.com/fish-shell/fish-shell/blob/master/history.cpp?:

ah, yes, forgot about the delay.
well it doesn't contradict what i said, it's just not immideate.

i suppose it would be nice to have a command to force a history sync. i
don't know what kind of effort would be involved...

greetings, martin.
