Correct.  All I'm asking for is a spec, and then it should be
straightforward to implement.

Does it sound ok to everybody that

AC_CONFIG_FILES(foo)
AC_CONFIG_COMMANDS(foo, echo foo, echo bar)

is the same as

AC_CONFIG_FILES(foo, echo foo, echo bar)

?

Or do you think it might mask clashes, and should trigger an error (as
is the case now), and *_HOOK would be better.
