Dear Robert, Bram and vim-multibyte teams,
I make another patch based on the Robert's work.
I make some code clean up.
screen_char_needs_redraw() is becomes lighter.
(I also changed the function name shorter.)
And the function has no side effects now. (no char_bytes setting)
This patch is based on the original vim-5.6 source.
Please test the newer patch. I've just tested it in the MULTI_BYTE environment
in console mode(xterm) only. ^^;
Bram: please change the function names based on the vim naming convention.
Bram: I find another bug. in README_src.txt, it refers vim-5.5-*.tar.gz. :)
