How LibO, GDocs, and MSO shows changes

Attachment shows how LibO. GDocs, and MSO handles changes (second line for LibO
shows how the actual request could be improved).

Your banana/havana is only part of the question. We should consider
addition/deletion/replacement of single/multiple letters at the
beginning/middle/end of a word. And the question is also where the changed
letter is placed - before or after the new.

My take considering readability and least changes to the text:

Beginning, single & multiple letters: just add, or insert right of the replaced
letters (He -> -H-She)
End, single & multiple letters: just add, or insert left of the replaced
letters (him -> her-im- | steps -> stepz-s- compare GDocs and LibO in the
attachment)
Middle, single letter: insert and place the new letter right of the replaced
(behind -> be-h-kind)
Middle, multiple letters: replace the full word and show the new right-hand
(queit -> -queit-quiet | quite -> -quiet-quite) (here I would go further than
MSO just to make the algorithm simpler)
In case of addition/deletion of single and multiple contiguous letters I would
just do the changes but when more than one letter is changed on different
positions the full word should be replaced (Havana -> Havan+n+a | Hawana ->
Ha-w-vana vs. Hawana -> -Hawana-Havanna 

On the other what we have works not that bad for me. We should also consider
the input that might become strange; that needs some testing.
