[PATCH] type -w += suffix alias

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

This makes 'type -w' distinguish suffix aliases from regular aliases,
like bare 'type' already does.

Use-case: detecting programmatically whether the command word is indeed
a valid command word (see <https://github.com/zsh-users/zsh-syntax-highlighting/issues/126>)
