The main reason is that when you are merging lots of files (for  
example, when running FreeBSD's mergemaster), one can leave the  
middle and index finger of your left hand on the "1" and "2" keys,  
and have your right hand on Return/Enter, allowing for very rapid  
responses.  You can't easily hit both "1" and "9" using a single hand.

A second reason is that when sdiff shows the two-column display, most  
people would count these columns as "1" and "2", not "1" and "9". [1]

[1]: While a few people might count them as "0" and "1", or perhaps  
even "1" and "10", they are better served by having user-selectable  
keys rather than hard-coding the keys being used....
