If you want to deal with external files, you use FileStream, right?
In 3.8 gamma Squeak, the FileStream (sub-)instance you create via:

  FileStream fileNamed: 'foo.txt'.

creates the stream that is capable to absorb the end-of-line
difference.

  In 3.8 gamma, you can say:

	f := FileStream fileNamed: 'foo.txt'.
	f wantsLineEndConversion: true.
        f converter: Latin1TextConverter new.
	lines := OrderedCollection new.
	[(line := f nextLine) ~= nil] whileTrue: [lines add: line].
	f close.

no matter what line-end-convention foo.txt uses.   (You may want to use:

        f converter: UTF8TextConverter new.
).

  FileStream is a few exception where Squeak needs to deal with the
outside world.  And it is handled reasonably well.
