absorb: prompt user to accept absorb changes by default

Change the default absorb behaviour to print the changes out and then prompt
the user if they want to absorb the changes or not.

Providing the `-p` option still prints the result and exits.  A new `-a` option
is provided which applies the changes without printing them, giving the
equivalent of the old behaviour.
