As mentioned before, the proposed return value includes column numbers, it has more information than a unified diff. It should not be difficult to turn the returned information into a unified diff if really needed. Although I doubt it would be useful in more than a few cases. It's easy to think of all kinds of options to add to return the diff in various forms. But do we really need it? I rather just provide the basic functionality, what would be slow to do in Vim script, and return the result in a form that is easy to use for several purposes. -- >From "know your smileys": 8-O "Omigod!!"
