Yes, the above is the preferred format.  "Likewise", "ditto", etc. are
just useless noise, since you have to go to the first entry anyway to
understand what was done.

Also, please note that typing "C-x 4 a" in several functions without
adding any text after the colon will automatically extend the list of
names in parentheses, so all you have to do is write the description
of the change once after you type "C-x 4 a" in all the functions where
you made the same change.
