Thank you!

I am using Oh-My-Zsh and I found this, in ./lib/history.zsh:

## History command configuration
setopt extended_history       # record timestamp of command in HISTFILE
setopt hist_expire_dups_first # delete duplicates first when HISTFILE 
size exceeds HISTSIZE
setopt hist_ignore_dups       # ignore duplicated commands history list
setopt hist_ignore_space      # ignore commands that start with space
setopt hist_verify            # show command with history expansion to 
user before running it
*setopt share_history          # share command history data*


Seems like an odd default assumption to have.
