And the error was the use of TOK_SHR instead of TOK_SAR (to get
the old behavior, i.e. with value 2). I've pushed the change to
TOK_SAR. The code is a bit ugly, though (I mean that the difference
between TOK_SAR and TOK_SHR is not clear for tokens, as the
signedness is just semantics, not something lexical).
