        Fix for this bug:

        The styling code did not move to the next node when the starting position was
        at the last offset of a node. Instead, it styled it. Clearly wrong. Solution
        is to borrow a check from the delete algorithm. Though I call caretMaxOffset(),
        which I consider deprecated, it is still the simplest and most strightforward
        way to ask the right question for this kind of problem.

        * khtml/editing/htmlediting.cpp:
        (khtml::ApplyStyleCommand::applyInlineStyle): Fixed, as described above.
        * layout-tests/editing/style/style-3998892-fix-expected.txt: Added.
