最近新建一個倉庫，push時遇到如下問題，試了好多方法，最后在stackoverflow上找到解決辦法了，可是在開始時就試過這方法，但不成。至於為嘛出現的這種錯誤，還是不明白原因。
git.exe push --progress "origin" release:refs/for/release%r=xxx

git did not exit cleanly (exit code 1) (593 ms @ 2015/5/15 9:51:12)
解決方法：git push --no-thin origin HEAD:refs/for/release
Git還得花時間研究下，剛接觸不久，小菜鳥一枚，好多原理都還弄不明白
