+'GIT_FLUSH'::
+ If this environment variable is set to "1", then commands such
+ as git-blame (in incremental mode), git-rev-list, git-log,
+ git-whatchanged, etc., will force a flush of the output stream
+ after each commit-oriented record have been flushed. If this
+ variable is set to "0", the output of these commands will be done
+ using completely buffered I/O. If this environment variable is

+ based on whether stdout appears to be redirected to a file or not.
