That is simply because a layout that has .git and its containing
directory (i.e. the working tree) on a separate filesystem when we
run "git init" is not supported, and more importantly, we do not
want to step outside ".git", which is the simplest and safest way to
avoid touching the end-user data that sits in the working tree.
The code comment is about checking the filesystem that houses both
the working tree and ".git"; if the user later wants to turn .git
into a separate mount point, or if the user wants to use GIT_DIR and
GIT_WORK_TREE to create a funny layout, the user should know how to
muck with ".git/config" to adjust to the peculiarity.
