You will be fine if you remember that these plumbing commands work by first cd'ing to the top-level of the working tree (and adjust the paths given from the command line by prefixing the prefix to them).

The input lines that come from --exclude-per-directory should go through the prefixing, but -X=<file> makes that single file affect the whole operation. It does not make sense to allow where you are to affect behaviour of the command, i.e. in these two invocations of ls-files:

	git ls-files -X /var/tmp/exclude -i
        cd example && git ls-files -X /var/tmp/exclude -i

if the same line in /var/tmp/exclude meant completely different things, it would be crazy.
