Hi Derek,

The main problem is to keep the semantics of Autoconf active here.
Each (quoted) argument ought to be evaluated once, to perform macro
expansion once.  Your proposal break this rule.

For instance

m4_define([FOO], [Foo Foo Foo Foo Foo Foo Foo Foo])
AC_INIT
echo "AC_HELP_STRING([FOO], [FOO], [FOO])"

Ought to work.  But technically, this is nearly impossible in all the
cases (such as the one you mention) without changing M4.  Once someone
has time...
