Huh.

I've been in this "use the old stuff for portability" camp for some time,
but now that you mention it....I can't think of any systems I use that
require resorting to old-style shell-isms.

What an interesting epiphany. It reminds me of the time when first I
realized that continuing to write K&R-style C was no longer necessary, as
everything that I used had an ANSI-compatible compiler and supported
function prototypes.

Seeing backticks in the rearview mirror is a welcome change.
