Ok, I've worked through this issue a few times, and I think the whole
paragraph should simply be deleted and instead replaced with a statement
that "Lines that end in a forced break must not be justified, and are
instead aligned as if text-align had its initial value." or somesuch.

The original intent of the paragraph, afaict
was to clarify that force-wrapped lines do not get justified and are
instead start-aligned.

But with the introduction of 'pre-line', 'pre-wrap', and the application
of 'white-space' to inline elements, this paragraph now introduces an
arbitrary restriction for, afaict, no good reason. If the author is
specifically requesting both preserved white space and justification,
then he should get justification on any soft-wrapped lines. (If he
didn't want justification, he would simply not specify justification.
And if he wants justification on hard-wrapped lines, then he can use
the additional justification controls from CSS3 Text.)

If inheritance through <pre> is a problem, then we should address that
in the default style sheet.

   pre { text-align: initial; }
