Comparing various sieve scripts I concluded (but I didn't actually
test it) that you need a stop; in your if or elsif clauses in case you
have an else clause with an explicit keep; -- IMHO a behaviour
violating RFC 5228.

	RFC 5228, Section 3.1

	...

	If the test of the "if" is false, it evaluates the test of the
	first "elsif" (if any).  If the test of "elsif" is true, it
	runs the elsif's block.  An elsif may be followed by an elsif,
	in which case, the interpreter repeats this process until it
	runs out of elsifs.

	When the interpreter runs out of elsifs, there may be an
	"else" case. If there is, and none of the if or elsif tests
	were true, the interpreter runs the else's block.

Stefan, can you enlighten us?
