-# In case `local' is not supported by the shell, provide a function
-# that simulates it by simply performing the assignments.  This means
-# that we must not expect `local' to work, i.e., we must not (i) rely
-# on it during recursion, and (ii) have two local declarations of the
-# same variable.  (ii) is easy to check statically, and our test suite
-# does make sure there is never twice a static local declaration of a
-# variable.  (i) cannot be checked easily, so just be careful.
-#
-# Note that since we might use a function simulating `local', we can
-# no longer rely on the fact that no IFS-splitting is performed.  So,
-# while
-#
-# foo=$bar
-#
-# is fine (no IFS-splitting), never write
-#
-# local foo=$bar
-#
-# but rather
-#
-# local foo="$bar"
