It's not just a parser implementation detail. Lists are *defined* to
terminate on newlines. From zshmisc(1):

    A list is a sequence of zero or more sublists, in which each sublist
    is terminated  by `;', `&', `&|', `&!', or a newline.

In your second example, `[ -e file1 ]` constitutes a list.
