Yes, you did this with the commit,
test_cmp() {
test $# -eq 2 || BUG "test_cmp requires two arguments"
if ! eval "$GIT_TEST_CMP" '"$@"'
then
test "x$1" = x- || test -e "$1" || BUG "test_cmp '$1' missing"
test "x$2" = x- || test -e "$2" || BUG "test_cmp '$2' missing"
return 1
fi
}
and I do not immediately see why "test -e" shouldn't be "test -f".
It should ideally be "stdin is OK, otherwise it must be a readable
regular file".
Thanks.
