bug#14771: 24.3.50; Unable to scroll one line at time at window edges.

[Keith David Bershatsky]

Within a recent revision to the Emacs Trunk (probably the last month or so), 
the default behavior of scrolling one line at a time when reaching the window 
edges (top / bottom) was disabled.  (setq scroll-step 1) does not fix this.  
Setting scroll-conservatively to a high number works only with the down arrow 
key, but the up arrow key causes emacs to temporarily freeze when reaching the 
top window edge -- i.e., the dreaded spinning wheel on OSX.

Thanks,

Keith
