Hmm.  That means my current AM_COND_IF patch will treat

  AM_COND_IF([OUTER],
             [$outer_action
             AM_COND_IF([INNER],
                        [$inner_action])])

correctly but mistreat

  AM_COND_IF([OUTER],
             $outer_action
             AM_COND_IF([INNER],
                        [$inner_action]))

That's a bit ugly, and certainly deserves mention.

Cool.

Happy Easter,
