This fixes the --interactions option when using pacoxph. With the
introduction of the (mathematically useless) \mu in the Cox model (which
was introduced to fix bug 1266 (pacoxph with no covariates) on R-forge),
the extra parts of code where we adjusted for the missing \mu were
inadvertently kept. Cox + interactions must have been broken since then.
