end of line conventions....

[Ducasse]

MicDocumentWriter >> usedNewLine
	"Return the encoded new line. Useful for tests."
	^ canvas stream usedNewLine

MicOutputStream >> usedNewLine
	^ self configuration newLine

So the convention is based on the configuration.

In particular it means that it is unclear how we can use

MicDocumentWriter >> crlfAsNewLine

	canvas crlfAsNewLine

[Ducasse]

OK so this means that crlfAsNewLine is needed in case we want to really use crlf.
I will update the comment.
