This patch is exteding the specs matcher and adding support for the ">"
and "<" operators. Prior to this patch, only the "equal" forms were
supported (">=" and "<=").
It also looks inconsistent because for the "s" prefixed operators all
the 4 forms are supported already: "s<=", "s<", "s>=" and "s>".
