B19.1 bug: `du' miscounts disk usage and ignores .* files

Hi,

`du' seems to be miscounting disk space by a factor of two on NT 4.0SP3
on a NTFS disk.  Actually, `du -h' *does* work, but both `-m' and `-k'
misreport the sizes:
  $ du -ks
  3337	.
  $ du -ms
  3	.
  $ du -hs
  6.3M	.

Another problem is that in its recursion, `du' skips directories that
start with `.' in their name, e.g. `.srt'.  It *does* include them in
the first level directory, e.g. in `.' if I invoke `du .'.  But it
misses them in all nested directories:
  $ du
  21	./.srt/i586-pc-cygwin32-winnt4.0/msvc++-5.0/.srtdb/deps

With sufficient thrust, pigs fly just fine.  However, this is not
necessarily a good idea.  It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead.  --RFC1925, "The Twelve Networking Truths"
