True. Though what about shells such as the Dos one which don't have
something like `...` AFAIR? Also, a slight difference is with `...`
the echoed command shows the sub-command, whereas with $(shell) it
shows its output. Not saying either one is better in general, but
perhaps depending on the situation someone might prefer one or the
other.
FWIW, the way I came across it now wasn't actually from my own usage
in a Makefile, just by thorough testing of the features.
