The maximum length of a line that can be displayed in Plain Text view was increased to 1,024,786 characters as of version 6.0 SP1. This is likely long enough (or probably far longer in fact) than anything a human would want to try to read or try to edit in that view.
Note that this is for the visual representation of the document in Plain Text view only. A document can still contain lines longer than this (usually when pretty printing is disabled) and the XML source will be just fine in both in Plain Text view and when the document is saved.
