Subject: [ruby-talk:04148] Inconsistent file access on Windows ports

My Wintoys seems to behave differently with two distributions and each time
not in a way I'm expecting:

  str = 10.chr+13.chr+10.chr+13.chr+"foo"
  outf = File.new("foo", "w")
  outf.write(str)
  outf.close

  inf  = File.new("foo")
  str2 = inf.read(8)

  puts( (str == str2), str.size, str2.size)
  p str, str2

  (str2.size).times do |i| puts str2[i] end

Outputs:

rbcw145\ruby test_3.rb
  true
  7
  7
  "\n\r\n\rfoo"
  "\n\r\n\rfoo"
  10
  13
  10
  13
  102
  111
  111


rbdj145\ruby test_3.rb
  false
  7
  6
  "\n\r\n\rfoo"
  "\n\r\nfoo"
  10
  13
  10
  102
  111
  111

Of these two, cygwin (rbcw) seems to be more consistent, and dj-version
loses latter ascii 13 somewhere.

In any case my hex editor outputs the file content as 
"0D 0A 0D 0D 0A 0D 66 6F 6F". And dir says the length of the file is 9.
Somehow both read and sysread (and writes) duplicate 10.chr to
(13.chr,10.chr) in real file.

I wonder what it should be. I'd expect "0A 0D 0A 0D 66 6F 6F", after all
that's what I'm trying to stuff there. 

I save you from the story how I did end up with this code, but let's say I
was trying to copy files by hand and my end result was few kilos fatter than
the original. The moral of the story is probably "always use original!" :)

Ps. I didn't post this to the bug list, because I didn't knew if it was a
bug, a feature or one of those bugs in my head.
