One semantic difference between the two versions is that replacing "a
macro" with "another macro" implies that the current macro cannot also
be the end macro.  But groff allows this.

.de repeat repeat
.  tm I repeat myself.
.repeat
.
.repeat

(Bonus points if you can guess without running the code whether this
puts "I repeat myself" on stderr twice or endlessly.  (I couldn't.))
