Well, maybe the doc ought to be adjusted, nevertheless, I think this
is the correct feature.  Being able to detect an error seems better to
me.  In addition, this is consistent with all the other AC_CONFIG.

So I don't plan to change this.  Please, help us improve the doc, but
if foo is optional, then the correct directives are

if test -f; then


if test -d foo; then
