The commit message should describe why the change is made, see

You should probably add a test for the new behaviour in
t/t4053-diff-no-index.sh.

This makes git diff --no-index $directory $file the same as
git diff --no-index $file $directory. Shouldn't these commands give
different results? (See the behaviour of diff in this case, and
compare it to the behaviour you introduced here)

Your MUA seems to have replaced tabs with spaces in this email. The
easiest way to get the formatting correct is the git send-email tool.
You should also try to sending the mail to yourself first and see if
it applies correctly with git am.
