[PATCH] msxml3: Remove CRs in domtext_put_data and add them in domtext_get_xml.

[Nikolay Sivov]

This needs more tests, for different msxml object versions, and for
different input document. It's possible that get_xml() returns original
document, so test loading non trivial document is necessary.

I remember looking at this some time ago, not for this specific report
but in general, and my conclusion was that the only way to generate
matching document is to duplicate node dumping in our code.
