Never mind, this is not at all obvious. On the other hand it is hard to
check for all these things (e.g. whether you have the same number of
atoms in tpr and xtc), and even if you could do these checks, you
sometimes want to keep the flexibility to use it programs with non-
matching files (if you think you know what you're doing which is a
common pitfall even for us core developers).
