I found that IO#read(length) don't convert "\r\n" to "\n" on 1.9.x

On ruby 1.8.6 (2010-02-04 patchlevel 398) [i386-mingw32]

irb(main):001:0> File.open('test.txt','r').read
=> "test\n"
irb(main):002:0> File.open('test.txt','rb').read
=> "test\r\n"
irb(main):003:0> File.open('test.txt','r').read(8)
=> "test\n"
irb(main):004:0> File.open('test.txt','rb').read(8)
=> "test\r\n"

On ruby 1.9.2dev (2010-03-31 trunk 27123) [i386-mswin32_90]

irb(main):001:0> File.open('test.txt','r').read
=> "test\n"
irb(main):002:0> File.open('test.txt','rb').read
=> "test\r\n"
irb(main):003:0> File.open('test.txt','r').read(8)
=> "test\r\n"
irb(main):004:0> File.open('test.txt','rb').read(8)
=> "test\r\n"

I think that File.open('test.txt','r').read(8) should be "test\n".

On 1.9, newline conversion has moved from stdin wrapper to encoding
translation layer, which stop working on binary read, so it's intended
feature.

I understand the feature.
But, in that case, the document of ios.read(length [,buffer]])
must be stated the difference when length is present or omitted.
