This is a one-liner that appears to originate from Andreas.  I'm not
clear on why trail first isn't the same as the current position, but I
checked and Eddie is right that the actual movement of the HandMorph
occurs AFTER this so the current position will be the start position. I
loaded this code and it appears to do the correct thing.

If this somehow breaks Genie then I'm of the opinion that there is a bug
in Genie and/or it is working around this bug and simply needs to be
updated to reflect this fix.
