Editign a document

[Germán Arias]

Editing a document with Ink, without adding new lines, only the first
characters added switch the document to status "edited". Then if you
save the document and you add new characters (without press return key)
the document status still remains as saved (not edited). And the option
"Save" at menu is disabled. Only adding new lines, switch the status
document to "edited". Is this the normal behavior or is a bug? If this
isn't a bug, then this mean that I need implement the methods to handle
status of a document, right?
