That seems very counterintuitive!  I'm taking it as a regular glob just 
as, I think,
anyone would.

I couldn't get any love from that.  What I do in my wrapper is this:

    echo -e "\n\e[31;1mACTIVE:\n\e[0m`whence -mv "$1"`"
    echo -e "\n\e[31;1mSHADOWED AND/OR LINKS:\
                  \n\e[0m`whence -sav "${1//'*'/}"`"

... which is a bit clumsy, but if I type ' i zsh* ' I want 'whence-ish' 
information on
the intuitive meaning of 'zsh*' and I want to see links, and 'shadowed' 
files
because they may very well be part of a chain of links, as is true 
above. But '-m'
won't permit '-s', and '-a' won't permit glob.  I hope that something more
friendly can be come up with. I hope it's " whence -as "zsh*" "
