I'm not completely certain that we are doing the 'right thing' here, but here 
is the argument:

This behavior is required for count from end (start on a frame N*Skip where N 
is an integer).
I would like how a given frame range looks to be independent of the starting 
frame.  So we do the same thing for all modes.
I can see times where one would or would not want this.  If there is any 
consensus, I would be willing to have it changed (for everything except count 
from end).
