New Revision: 288678
URL: https://svnweb.freebsd.org/changeset/base/288678

Log:
  Merge additional testcases and improvements to bin/ls/ls_tests from
  ^/user/ngie/more-tests.
  
  - Additional testcases added:
  -- ls -D
  -- ls -F
  -- ls -H
  -- ls -L
  -- ls -R
  -- ls -S
  -- ls -T
  -- ls -b
  -- ls -d
  -- ls -f
  -- ls -g
  -- ls -h
  -- ls -i
  -- ls -k
  -- ls -l
  -- ls -m
  -- ls -n
  -- ls -o
  -- ls -p
  -- ls -q/ls -w
  -- ls -r
  -- ls -s
  -- ls -t
  -- ls -u
  -- ls -y
  - Socket file creation is limited to the ls -F testcase, greatly speeding up
    the test process
  - The ls -C testcase was made more robust by limiting the number of columns
    via COLUMNS and by dynamically formulating the columns/lines.
  - Add `atf_test_case` before all testcase `head` functions.
