Source/WebCore:
The CSS WG resolved [1] to add a new value 'anywhere' to the 'line-break'
CSS property in order to allow additional breaking opportunities not
considered in the definition of the 'word-break: break-all'.

LayoutTests:
Some of the new tests added to verify the new 'line-break:
anywhere' feature and its different behavior to what 'word-break:
break-all' may provide, fail due to several bugs present in
current WebKit's trunk.
