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">
<string>
<literal " ">
<literal "\u0009">
</string>
</assignment>
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.
