[Split off from bug 11630, where this was not the main issue]

The testcase (attachment 11590) demonstrates that text-transform:capitalize
changes non-breaking spaces to normal spaces. In shipping Safari, Firefox and
Opera, there is a gap between the two 100x100 squares due to the text, which
includes non-breaking spaces. This is also the case in TOT if text-transform:
capitalize is not specified.

>From StringImpl::capitalize:
        // Replace &nbsp with a real space since ICU no longer treats &nbsp as
a word separator.

This was added in r13702 to address <rdar://problem/4502311>
text-transform:capitalize needs to 
treat nbsp as a regular space when ICU changes.

I think the solution might be as simple as copying from m_data[i - 1] instead
of stringWithPrevious[i] in the loop that copies the non-capitalized
characters.
