今天执行 git push 的时候报了如下的错误：
$ git push
Warning: Permanently added 'ssh.github.com,192.30.252.149' (RSA) to the list of known hosts.
对象计数中: 27, 完成.

error: pack-objects died of signal 13
error: 无法推送一些引用到 'git@github.com:mozillazg/mozillazg.com.git'
最后的解决办法是加大 http.postBuffer 的值:
$ git config http.postBuffer 52428800
http.postBuffer 的值的单位是字节， 52428800 = 1024 * 1024 * 50 即 50 M。
