For example, in the diff: http://en.wikipedia.org/w/index.php?title=Undeciphered_writing_systems&diff=375671540&oldid=372821363 The edit separated the second sentence as the start of a new paragraph and inserted the text, shown at the beginning of the green field, as part of the first paragraph. The second sentence and after, now a separate paragraph, is still shown highlighted in green. A search/comparison function inserted after the diff is formed which compares the pre-existing version and the diff output text, could unmark the pre-existing text from green to a nominal yellow color. This helps to distinguish text which has added from pre-existing text which has simply been shifted, moved, or transplanted. -SC
MediaWiki supports using different diff-algorithm programs. So if you find a diff algorithm that can do this, it may be possible to try that on a wiki (or your own (test) wiki) without having to change MediaWiki core. Would be nice if could have this by default! There are a lot of other bugs about issues and lackings in the default diff algorithm.
