  As far as I understand, there are three related queries here:


1. is-inside-git-dir
2. is-inside-work-tree
3. is-bare-repository

They are used to discern whether you are inside the repo/.git dir, or in
the work-tree.

If you are in a bare repository, the first one will happen to always be
true, but if you want to know whether you're in a bare repository or not,
the third one is the one to use.


Ah, okay, so some further testing then shows the following results:

tim@bigbox:~/tmp/git_test$ for loc in '.' bare_repo/ nonbare_repo/ 
nonbare_repo/.git nonbare_repo/empty_dir/ ; do pushd $loc 2>&1 
>/dev/null; echo In $loc; for test in is-inside-git-dir 
is-inside-work-tree is-bare-repository; do echo -n ${test}: ; git 
rev-parse --${test}; done; popd 2>&1 >/dev/null; echo 
''; done


In .
is-inside-git-dir:fatal: Not a git repository (or any parent up to 
mount point /home)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not 
set).
is-inside-work-tree:fatal: Not a git repository (or any parent up to 
mount point /home)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not 
set).
is-bare-repository:fatal: Not a git repository (or any parent up to 
mount point /home)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not 
set).


In bare_repo/
is-inside-git-dir:true
is-inside-work-tree:false
is-bare-repository:true

In nonbare_repo/
is-inside-git-dir:false
is-inside-work-tree:true
is-bare-repository:false

In nonbare_repo/.git
is-inside-git-dir:true
is-inside-work-tree:false
is-bare-repository:false

In nonbare_repo/empty_dir/
is-inside-git-dir:false
is-inside-work-tree:true
is-bare-repository:false

So EVERYTHING outside the repo fails.  The --is-inside-work-tree 
does return false (contrary to what I remember testing earlier) 
inside .git, and in a bare repo.  Okay, that makes sense.  Thanks!
