IMO autoconf should interfere with shell script writing as little as
possible. The confusion with the brackets is already trouble enough.

I mean, it's possible to find different syntaxes for shell scripts
at will. I could even reformulate
      IFS="     "
in XML like this:
      <assignment variable="IFS">
          <literal " ">
          <literal "\u0009">
but this is useless because the shell script syntax people are _used_to_
is the one with brackets and tabs and without quadrigraphs or XML tags.
