difftool -d not populating left correctly when not in git root

Hi,

looks like this broke between 2.9.2 and 2.9.3

cat ~/.gitconfig
[difftool "diff"]
     cmd = ls -l ${LOCAL}/* ${REMOTE}/*
     #cmd = diff -r ${LOCAL} ${REMOTE} | less

~/stuff/gittest> ls -l * d1: total 8 -rw-r--r-- 1 frank staff 16 2 Dec 14:30 test.txt

d2: total 8 -rw-r--r-- 1 frank staff 18 2 Dec 14:30 anothertest.tst

~/stuff/gittest> git status
On branch master

   (use "git add <file>..." to update what will be committed)
   (use "git checkout -- <file>..." to discard changes in working directory)

Note that left does not contain d1
