where it is legal. Hence (i) test M4sh in its own world, not
Autoconf's, and (ii), ahem, fix the bug :)

does not like `' instead of [].

(m4_expansion_stack): this, and change its value: instead of using
the pushdef stack to stack each *line* of the stack, each

display the current definition.

Of course this revealed numerous non updated uses of old macros in

But for the time being, keep `define' alive for Autoconf.
