The here-doc (<<-\EOF) form is definitely a good idea when the code is
part of an indented test body, whereas the multi-line double-quoted
string will be problematic since lines "b" and "c" will be indented
with TAB, which is undesirable here.
Even better for such a simple case would be:
test_write_lines a b c >out &&
In fact, Junio made this suggestion in the form of a code snipped much
earlier in this thread.

This is also an improvement, though test_write_lines would (again) be
even better for such a simple case:
test_write_lines x y z >f &&
