Is there a way to probe for this bug at runtime?  I.e., a way for
a script to determine whether the zsh binary that interprets it has or
hasn't this bug?

We need this in z-sy-h to choose between two codepaths (and we'd
rather not use is-at-least in case distros backport m0vie's patch).

Thanks,

Daniel
