This is only used by bash2.  You need "setopt HIST_IGNORE_DUPS" to get the 
zsh equivalent.  But if history ignores dups, then this ...

... is a no-op, because there won't be any dups to expire.

No, they don't need to be exported, the latter two just need to be set. 

(It doesn't do any good to both export them and set them in ~/.zshenv, 
because every zsh will re-read ~/.zshenv and clobber the environment 
value.  You'd only export them if e.g. they were set in ~/.zlogin, which 
is not read by non-login shells.)
