bug#7282: 23.2; [PATCH] Improve text composition by Input Methods on MacOSX.

[Keitaro Miyazaki]

It is quite difficult to compose "input text" of language
such as Japanese by Input Methods like "Kotoeri" on MacOSX,
because emacs does not show clause boundary of the "input text".

I made an attached patch which improves text composition
by making a highlight on active clause of the "input text".

See also attached screen shots which shows effect of this patch:

              clause boundaries are indicated by
              a highlight on active clause.
