That change looks like it can do only good, so I installed it into
Autoconf. Thanks.
I'm not sure about the documentation change. It's not yet clear to me
that we want to document AS_LITERAL_IF (the above example being one of
the gotchas). If we do want to document it we probably need to be
more systematic about it and its friends. So I left that alone for
now.
