Re: behaviour of git diff, GIT_DIR & checked out tree

Yes, this is fully expected.

The @{time} notation accesses the _reflogs_, which are purely local

Thanks of your reply; however I suspect this isn't the problem
here since I just tried with just master and I get the same thing.
To be clear, I'm doing this on the same machine with the same
user account as the git directory, just from a directory outside
the git tree, eg, the git tracked tree is in $HOME/V and I'm
in $HOME/A running

env GIT_DIR=$HOME/V/.git git diff master

As a guess without looking at the code, what I imagine
is happening is that git diff limits showing changes to the directory
tree below $PWD, and when $PWD isn't actually within the git
dir that ends up somehow as an empty tree.
