@Andrew thanks for the report.  Let me spell out the symptoms for the list:

In zshrc, «typeset -a zle_bracketed_paste=('' '')» and «unset
zle_bracketed_paste» have no effect if done before zsh/zle has been
loaded, because of zsh/zle's setup_() unconditionally assigns to the
parameter, even if it already exists and has a non-null value.

I looked into this yesterday, and guarding the assignaparam() call with
a paramtab->getnode() != NULL fixes the case that the variable is
already set by the time zsh/zle is loaded (e.g., if it's set in zshrc).
However, I haven't been able to make «unset zle_bracketed_paste»  have
any lasting effect if done before zsh/zle is loaded.  Is that achievable?
