Well, it's a judgement call, but in this case I think it makes sense
not to change the time stamps. The timestamps and intials give some
clues to help the reader understand who wrote something and when, and
it is good to preserve these clues when no functional change has been
made to the method.

The FixUnderscores procedure for changing assignment operators
to ":=" is another example where this makes sense.
