MultiByteFileStream bug on windows

Hello,
 I found a bug in the class MultiByteFileStream when Pharo(1.1-11411) running under Windows:
 The following code

 "(MultiByteFileStream new)
 wantsLineEndConversion: true;
 open: 'c: \ temp \ 1.txt' forWrite: true;
 cr;
 close.
 "

 File c: \ temp \ 1.txt contains 3 characters (cr lf lf) instead of two (cr lf).
 This is due to the fact that the method MultiByteFileStream>> nextPut: There is a double conversion of Cr to CrLf.
 I think this can be corrected as follows:

 "
 MultiByteFileStream>> nextPut: aCharacter
       aCharacter isInteger
                 ifTrue: [^ super nextPut: aCharacter].
       (wantsLineEndConversion == true and: [lineEndConvention notNil]) "# doConversion is inlined here"
                  ifTrue: [
                              aCharacter = Cr
                                     ifTrue: [converter nextPutAll: (LineEndStrings at: # cr) toStream: self]
                                     ifFalse: [converter nextPut: aCharacter toStream: self].
                              ^ aCharacter].
       ^ Self converter nextPut: aCharacter toStream: self
 "

 Sincerely,
