Well, partly it's a documentation problem, partly new behavior, partly
it may also be a bug.  The problem is that previously, \hspace was
implemented as going forward by the stated amount minus a space width.
In combination with the following interword space (_iff_ there was an
interword space following, otherwise \hspace would go wrong), this
resulted in 0.1 amounts of space.

\fill-line stretches the interword space.

Now \hspace has been changed to only actually take the required space
and it is _not_ getting surrounded by word space.  So there is less
opportunity for stretching.  Now \fill-line is not yet doing everything
right anyway, and that's
<URL:http://code.google.com/p/lilypond/issues/detail?id=3504>.  So there
will still be changes how the above works out.  But it's not clear that
it will, or that it indeed should work exactly as before.
