This uses code that is already in Pharo:

'/tmp/foo.txt' asFileReference readStreamDo: [ :readStream |
�� �� �� �� | lineReader |
�� �� �� �� lineReader := ZnLineReader on: readStream.
�� �� �� �� Array streamContents: [ :output |
�� �� �� �� �� �� �� �� | line |
�� �� �� �� �� �� �� �� [ (line := lineReader nextLine) isEmpty ]
�� �� �� �� �� �� �� �� �� �� �� �� whileFalse: [ output nextPut: line ] ] ]

Works with any line end convention. Check the class comment of ZnLineReader.
