vim-patch: 7.4.330

be slow.
Solution:   Add matchaddpos() to highlight specific positions
efficiently.

vim-patch: 7.4.362

Problem:    When matchaddpos() uses a length smaller than the number of
bytes in the (last) character the highlight continues until the end of
            the line.
Solution:   Change condition from equal to larger-or-equal.
