Re: 'whence' question

[Ray Andrews <rayandrews@eastlink.ca>]

Got that patch.  It works as advertised but I noticed this:

    $ whence -vam "zsh*"                       << QUOTED
    zsh is an alias for /usr/local/bin/zsh
    zshh is an alias for /usr/local/bin/zsh    << CATCHES ALIAS
    zsh-RayStyle1 is a shell function       << CATCHES FUNCTION
    zshh is a shell function                      << CATCHES FUNCTION
    zshh is /usr/local/bin/zshh                    << CATCHES SCRIPT
    zsh is /usr/local/bin/zsh
    zsh-RayStyle1 is /usr/local/bin/zsh-RayStyle1    << CATCHES BINARY
    zsh is /usr/bin/zsh
    zsh is /bin/zsh

    $ whence -vam zsh*                        << UNQUOTED
    zsh is an alias for /usr/local/bin/zsh
    ?  zshh  ...                                        << MISSES ALIAS
    ?   zshh ...                                        << MISSES FUNCTION
    ?   zshh ...                                         << MISSES SCRIPT
    zsh is /usr/local/bin/zsh
    zsh is /usr/bin/zsh
    zsh is /bin/zsh
    zsh-RayStyle1 is a shell function                        << CATCHES
    FUNCTION
    zsh-RayStyle1 is /usr/local/bin/zsh-RayStyle1        << CATCHES BINARY

I know that '-m' arguments are supposta be quoted, but, apart from the 
above,
I haven't found any situation where it seems to make any difference.  
Why would
it miss 'zshh' but find 'zsh-RayStyle1', and why do the quotation marks 
change
the order?

binary 'zsh-RayStyle1' might be found in both cases because it's linked:

     lrwxrwxrwx 1      28 2014-11-10//13:39:57 zsh -> 
/usr/local/bin/zsh-RayStyle1*

... but it still seems strange.  And the situation with the aliases and 
functions is
hard to understand. Both functions just echo their own name, so it's not 
the
contents.  For now the moral of the story is to always quote, but why would
one ever *not* quote?  I mean is there some valid use of it unquoted, or 
is that
just always wrong?  If always wrong, they can we 'autoquote' some how?
Complicated! And there's always another gotcha.

The above is not rigorous, but any clarification is welcome.
