I did give mksh a spin. It didn't fly with pkgsrc because it's
handling of the "echo" shell builtin is broken. At least it deviates
from BSD and SUSv3 sh(1). Try echo '\x40' under mksh.
We could probably hack it but I opted for pdksh for now because it's
more familiar and definitely time proven even though there are some
well known bugs lurking within it.
