fails to show diffs with git when changed file is in a parent directory

[nschaeff]

For instance, within the diffuse main git directory:

diffuse -c 613381    # shows the modified file as expected, which is in the current working dir
cd src
diffuse -c 613381    # FAILS to show the modified file, which is in the parent dir

I've learnt to think of this as a feature rather than a bug: only files in the current subdirectory are shown, so if I change a lot of files and only want to see changes in a subset, it's easy.
If you like, you could write a wrapper along the lines of

cd $(git rev-parse --show-cdup)
diffuse "$@"
cd -
