Add --log-size to git log to print message size
With this option git-log prints log message size just before the corresponding message. Porcelain tools could use this to speedup parsing of git-log output. Note that size refers to log message only. If also patch content is shown its size is not included. In case it is not possible to know the size upfront size value is set to zero.
