a GIT_DIR set on the command line or in the environment.
(Useful for excluding slow-loading network directories.)
+'GIT_DISCOVERY_ACROSS_FILESYSTEM'::
+ When run in a directory that does not have ".git" repository
+ directory, git tries to find such a directory in the parent
+ directories to find the top of the working tree, but by default it
+ does not cross filesystem boundaries. This environment variable
+ can be set to true to tell git not to stop at filesystem
+ boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect
+ an explicit repository directory set via 'GIT_DIR' or on the
+ command line.
