I think that 2.03.0(20) must be broken then. This isn't a bug. The quoting
rules used in a `..` are different than the rules in '...'. This fails on
every system that I tried this on. The problem is that the \ handling is
done in the `...` before the '...'. This is a typical problem with quoting
in a shell script.
