+'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.
