'whence' question

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

This seems right, the '-a' switch doesn't take wildcards:


     $ whence -a zsh
   /usr/local/bin/zsh
   /usr/bin/zsh
   /bin/zsh

... however the '-m' switch accepts wildcards:


   $ whence -m "zsh*"
   /usr/local/bin/zsh
   /usr/local/bin/zsh-ok
   /usr/local/bin/zsh-test1
   /usr/local/bin/zsh-test2-orig-rebuild
   /bin/zsh4
   /bin/zsh5

... yet, although '/usr/local/bin/zsh' is found, all of the other files 
found by
'whence -a zsh' above are missed. How is it that '/usr/local/bin/zsh' 
matches
'zsh*' but '/bin/zsh' does not?
