Do you mean something like this?
$ cd docs
$ edit orderfile
$ git diff -Oordefile
$ cd subdir
$ git diff -O../orderfile
Path-like parameters and values given by the end user should be
relative to the directory where the end user is (i.e. both -O
parameters in the above example name docs/orderfile). All Git
processes, even the ones that are capable of being run from a
subdirectory, are supposed to first chdir to the top level of the
working tree before doing anything else, and adjust the path-like
things they get from the end user from the command line accordingly.
By the time diffcore_order() to prepare_order() callchain is called,
we certainly should have passed that chdir already, so the value of
the option needs to be prepended with the "prefix" when parsed.
The value specified for the diff.orderfile configuration can just be
a path relative to the top level of the working tree, I think.
