* NEWS: Document that m4wrap/m4_wrap might not be LIFO.

Browse Source 
* doc/autoconf.texi (): Likewise.
Rework example of m4wrap token-pasting trouble so that it doesn't
care whether it's LIFO or FIFO.
Fix some "contrary to"s that are awkward in English.

* Major changes in Autoconf 2.59e
** Autoconf no longer depends on whether m4wrap is FIFO (as Posix requires)
or LIFO (as in GNU m4 1.4.x). GNU m4 2.0 is expected to conform to Posix
here, so m4wrap/m4_wrap users should no longer depend on LIFO behavior.
