mdrun does whatever the .tpr and command line options tell it. mdrun
knows about nothing (e.g. the forcefield files) that would permit it
recognize a "difference". Even if it could recognize such, silently
doing something else would be the way madness lies... grompp is pretty
good at noticing things that might be astray and giving suitable feedback.
