Did it get applied?

Since I stumbled over the same issue and spend a lot of time debugging
for nothing :-) I now understood with off-list help from Soeren that
t.register comes with two modes:

- Mode 1: assigning timestamps to maps only
- Mode 2: registering maps in the space time dataset

I think that the best would be to print these two messages
respectively when invoking t.register without or with "input="
parameter. Like r.sun does...
