	Yes, the variable is unsigned, and test tries to see, if it
	contains a negative number indicating non-change of value..

	Yes, I must see if I can do anything about the over-ambitious
	focus/defocus routines -- so that you can then use normal alias:
		... cat >> /tmp/archive.test"

	The mailbox program blows up at doing an alloca() of
	message size, which may become impossible with large
	message..   The sad/happy part is that the alloca()
	it does it completely unnecessery.
