原來可以查error msg, 多謝指點

原因出在無法執行diff (從沒想過這種可能性...Orz),
不知道為什麼沒有_vimrc時vimdiff會找到diff,
( c:\Program Files\Vim\vim63\diff.exe )
它應該是這麼做吧

     cmd /c "c:\Program Files\Vim\vim63\diff.exe -a --binary" FILE1 FILE2

但有_vimrc時它不用上面的做法, 而是直接cmd /c "diff ..."
於是我把diff.exe複製到system path裡其中一個目錄後, 問題就解決了

雖然很鳥, 姑且能用啦 ^^"
