+       * util/texi2dvi: Update DVIPSHEADERS so that dvips finds its
+       special headers.
+       Don't rely on non-IFS splitting when using local.
+       Maybe we should just not use local at all.
+       Or never use it to assign at the same time: declare, then assign.
+       * util/local.test: Check that "local" is used properly with quotes.

        Use hevea more like we use tex itself, no longer as a tool
        that does everything magically.
        * util/texi2dvi (run_hevea): Remove trailing spaces in the

+# In case `local' is not supported by the shell, provide a function
+# that simulates it by simply performing the assignments.  This means

+# 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
