'GIT_FLUSH'::
If this environment variable is set to "1", then commands such
as 'git blame' (in incremental mode), 'git rev-list', 'git log',
- and 'git whatchanged' will force a flush of the output stream
- after each commit-oriented record have been flushed. If this
+ 'git check-attr', 'git check-ignore', and 'git whatchanged' will
+ force a flush of the output stream after each 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
not set, Git will choose buffered or record-oriented flushing
