I'm really not that much of a fan of either method.  Both fail if the 
auhtorized_keys file has any customizations (e.g.  from="" in front of the 
key.  Something I tend to do out of habbit after moving a key up to a new 
server).

If anything I'd rather see a solution where it it looks at the 
RSA/DSA/RSA1 key proper without any prefix logic and not insert a new 
entry if it finds one (with a nice message to that effect as well).

The other two solutions are to me are no better than the existing behavior 
in this regards.
