Hello,

I'm using mathematica 2.2 (Unix), and i'm trying to do pattern 
matching with repeated patterns.

This example produce the result i want :

	In :  {a,a,a,b} /. {a...,b} -> Hello
	Out : Hello

But this one don't :
	
	In : {b} /. {a...,b} -> Hello
	Out : {b}

I was hopping :     Out : Hello

Why doesn't work it ???
