I'm not sure what you're hollering about.  Searching all forms has
nothing to do with whether the search is for a literal string (which
is the default) or for a pattern (which requires the -m option to be
explicitly stated).  "All command forms" means aliases, reserved
words, and functions, and your example found those aliases.

I'm 99.75% sure that you'd see

$ echo zsh*
zsh
zsh-RayStyle1

and that this is entirely the reason you get the above result from whence.

Well, yeah.  You did not specify -m and there is no command or
function whose name literally is zee ess aitch star, so whence found
nothing.

Well, no, they don't become files, the become whatever is on the
right-hand-side of the alias.

% alias zsh='echo good golly miss molly'
% whence -a zsh
echo good golly miss molly
/bin/zsh

It's not the fault of "whence" that you don't find this to be as
useful as the -v output.
