Subject: [PATCH] Fix regression introduced in d468fcbb / OTP-14816

The ~p format specifier made file:consult/1 hysterically slow on one
of our test machines that had a unicode character in the root of the
code path; all paths were printed as lists and indented with way too
much whitespace.

Using ~w avoids this issue by never indenting.
