Subject: Teach c:ls/1 to show non-directory files

In an email to erlang-questions, Bengt Kleberg wrote:

    When I use c:ls/1 it reminds me so much of Unix "ls" that I
    expect c:ls("filename") to work. The resulting error surprises
    me every time (not the same day).

While teaching c:ls/1 to show non-directory files, update the
error handling to make use of the POSIX error codes from
file:list_dir/1 and file:format_error/1 (which had not been
invented when the c module was first implemented).
