Consider having —

% unset foo
% echo $foo

— highlight the expansion $foo as an error/warning, since the parameter is unset.

'main': Apply the parameter expansion logic regardless of the type
f8a0395 
The existing check was bogus: parameter expansion doesn't depend on
whether there happens to be a command literally called «$foo».

This enables the parameter elision logic to kick in for words not in
command position.

Fixes zsh-users#239.

Reopened since #718 fixes this specifically, but not all of #509.
