vertical-motion behavior change

[Dan Nicolaescu]

Sometime in the past month the behavior of (vertical-motion 0) has
changed. 
For sources checked out of CVS on Nov 1st, (vertical-motion 0) would
move the point to the beginning of the line. 
For the current CVS sources (vertical-motion 0) would not move the
point. 

term.el relies on the old behavior in a few places, and not it does
not work correctly anymore...

Is this change intentional, or is an unwanted side effect?
