I think an example of the idea is this:

You open a live data source with -n 1000, but when you open it, there are only 
100 frames in it.  You see all 100 frames, with the displayed range growing.  
If you did nothing, the range would keep expanding, until you see frames 0 - 
999, then things would start scrolling (1-1000, 2-1001, etc...)

But, when the file is only 500 frames long, you hit 'read from end'.  Now you 
start scrolling, limited to 500 frames (1-500, 2-5001, etc).

The correct behavior would have been to not change the requested number of 
frames, but to only set count from end (which was already set in this case).

This example is not a big deal, but if you have multiple data sources, etc, it 
could be.
