It occurs to me that $options et al. predate the += syntax, so this may
just have been overlooked when adding array-append.

} For future reference, James (who reported the original bug offlist) has
} since reported another symptom:
} 
} % autoload -Uz compinit; compinit; setopt listambiguous; options+=()

So here's my question ... why would you ever attempt to append to the
options parameter, empty append or otherwise?  The options hash always
contains all possible valid keys; you can't add/delete a key; you can't
duplicate a key; so it absolutely never makes sense to append options.

I was half of a mind to flat out make it an error, as these are ...

torch% options[bogus]=on      
zsh: no such option: bogus
torch% options[shwordsplit]=
zsh: invalid value: 

... until I realized that all the other zsh/parameter hashes had the
same problem and some of them *could* sensibly be appended.
