Reason: test(1) can behave funny if the argument starts with
a hyphen-minus so when using test or [ instead of the secure
[[ of Korn shell use the x"=E2=80=A6" =3D x"=E2=80=A6" form.

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh
