Through experience with both existing site use of text-overflow, and
testing existing implementations[1], it's become clear that
text-overflow with a single value must only apply to the end line
edge, rather than to both left and right line edges.

In particular, there are numerous sites that apparently depend on
start edge ellipsing NOT occurring when there is a single value (e.g.
cases where a negative text-indent is combined with left padding, thus
causing overflow of the text, but not any rendering clipping).

In addition, existing implementations (IE, Opera, Safari) consistently
apply a singular text-overflow value to only the right edge for LTR
text, and in most of those (IE, Safari) to only the left edge for RTL
text.

Thus I've made the respective change in the CSS3-UI text-overflow section:

from: a single value applying to both left and right edges
to: a single value applying only to the end line edge.
