 # We require $(...) support unconditionally.
+# We require non-surprising "local" semantics (this eliminates dash).
+# This takes the admittedly draconian step of eliminating dash, because the
+# assignment tab=$(printf '\t') works fine, yet preceding it with "local "
+# transforms it into an assignment that sets the variable to the empty string.
+# That is too counter-intuitive, and can lead to subtle run-time malfunction.
+# The example below is less subtle in that with dash, it evokes the run-time
+# exception "dash: 1: local: 1: bad variable name".
 # We require a few additional shell features only when $EXEEXT is nonempty,
 # in order to support automatic $EXEEXT emulation:
 # - hyphen-containing alias names
