Okay,okay, I give in. To settle this again, I looked it up, and among
the options to -chainsep is 'interactive'. If you use that you're
prompted whether or not to separate at the breaks pdb2gmx detects.
That allows you to merge chains. I guess there'd be sense in just
having an option 'no' to merge everything, but that's for the
developers to pick up ;)
