In so far as a code comment can be considered code, removal of an
obsolete code comment can be referred to as removal of dead code.
So the subject seems pertinent to everything contained in this
patch from my point of view.

Frankly I don't consider removal of a 2 line code comment worthy a
commit of it's own, so if this is indeed a concern, I'd rather drop
it from the patch and leave the obsolete code comment in the file
for removal at some other date.
