[Wikipedia-l] Save Draft button

[Felipe Sanches]

I suppose that if a user start editing an article that has got a draft
written by somebody else but that wasn't yet commited, then mediwiki
could warn this user about the existence of this draft, possibly also
showing its contents to the new contributor so that he may opt to use
it as a basis for his contribution. This way we can minimize conflicts
that would happen due to the draft feature otherwise.
