	The test suite are sometimes assigning timings incorrectly.
	Reported by Henk Krus.
	Diagnosed by Nicolas Joly.

	* lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
	AT_help_all.
	Instead of making AT_help a sequence of assignments to grow
	$at_help_all, just make AT_help_all be the growing contents of
	$at_help_all, and make a single assignment in...
	(AT_INIT): here.
	(at_times_skip): Flip the meaning and rename as...
	(at_times_p): this.
	(AT_INIT): When summarizing the test that ran, remove

	executables, not bin/ executables!  Otherwise all the magic needed
	to find non installed files is turned off.  This caused a failure
	of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
	as found in its environment (sent by tests/autoreconf): pointing
	to bin/autom4te that could not find its files.

	the sake of "mv" program that are interactive when overwriting a
	-w file.
