It is the case. Every shell I've ever heard of does ``, the $()
thing showed up with the Korn shell and got propagated into various
other shells. I believe `` is more widely supported, and for a
maximally portable shell script (which admittedly this does not
need to be) is thus superior wherever it will do the job. If
one of BB's own shells doesn't support $() then that right away
tells you which style to prefer for this script.
