[PATCH] imm32: Added some unit test cases

[Michael Jung]

With builtin imm32 Excel 2003 Viewer hangs when clicking on a cell in an 
open spreadsheet. Excel Viewer calls ImmNotifyIME to cancel the 
composition string, which causes builtin imm32 to post a 
WM_IME_COMPOSITION messages, which causes Excel Viewer to call 
ImmNotifyIME again...

Turns out native imm32 does not post a WM_IME_COMPOSITION message if the 
composition string being canceled is empty (Tested on Vista with the 
attached testcase).

I've got a simple fix for this problem in my git tree. However, being 
totally ignorant of languages that use non ascii symbols besides the 
german umlauts, I don't know a thing about IME or XIM.

Aric, since it seems you are at it at the moment anyway, would you mind 
having a look on how to fix this properly?

Thanks,
