+ Simplification by Jim Meyering.

# We require $(...) support unconditionally.
+# We require that the printf built-in work correctly regarding octal escapes;
+# this eliminates /bin/sh on AIX 7.2.
# We require non-surprising "local" semantics (this eliminates dash).
# This takes the admittedly draconian step of eliminating dash, because the
# assignment tab=$(printf '\t') works fine, yet preceding it with "local "
# ? - not ok
