New options:

  -1   Disable columnizing.

  -c   Sort by file status change time.

  -C   Column directory entries.

  -h   Show file sizes with magnitude suffixes such as 42.3K.

  -r   Sort entries in the opposite order.

  -R   Recursively list directory contents.

  -S   Sort by file size in decreasing order.

  -u   Sort by access time.

  --color=always|auto|never
       Control whether colorizing is enabled.

The output is now natively columnized instead of running a column(1)
subprocess. Multiple operands are now implemented correctly (directory
contents are columned separately rather than their concatenation, the name
of each directory is printed prior to its content, ...). The file owner and
group names are now shown rather than a hard-coded root. Long listings are
now properly aligned. Mixing file and directory operands works correctly
now. Columnizing is now vertical rather than across. Clean up the source
code and remove cruft. Stat information on directory entries are read once
only now, which which fixes an incosistent sort race condition when sorting
according to lstat. Move to the openat paradigm.
