This fits with the fact that heirloom vi also does it. It
contradicting the POSIX standard explains why no-one else does
it, except perhaps commercial Unixes/OpenSolaris with a vi
independently derived from 4BSD vi.

Note: Ubuntu's "elvis-tiny", which was the version of elvis I
actually tested, has far more simplistic and clearly incorrect
behavior - it _always_ deletes the newline when deleting the
last word of a line, and fails entirely on the last word of the
last line. I've since downloaded a proper version of elvis and
it behaves the same as all the other clones apart from vim.

Maybe there should be a compatibility option to control this
behavior.
