Cgywin Git
Let git show English message and handle Chinese pathname correctly.
Open Cygwin, select option->text->locale character,  set zh_CN, GBK.
Add export LC_MESSAGES="en_US.UTF-8" to .bashrc.
For the meaning of LC_MESSAGES, refer to:
- Why “LANG=C”? (not D or E or F)
- C library function - setlocale()
- man 3 setlocale
