Writer : Undo problem(Japanese IME)

[Naruhiko Ogasawara]

Hi Hidemune, *

Some additional information:

1. To make the bug be tracked easier, I filed the bug:
https://www.libreoffice.org/bugzilla/show_bug.cgi?id=87500

2.  in Japaese ML:
http://listarchives.libreoffice.org/ja/discuss/msg03302.html
Hidemune said that BreakIteratorImpl::nextCharacters() handle
the last control code incorrectly in Japanese Windows environment,
and there are several code to call BreakIteratorImpl::nextCharacters()
same way.

If so, I think we should be correct BreakIteratorImpl::nextCharacters()
(or its subclasses) instead of SwBreakIt::getGraphemeCount().

How do you think?

That's because the patch is in the ML, not in Gerrit.
