Spotted at Lobsters is a thread about a stackoverflow question on man; why does running "man -w" report "gimme gimme gimme" when run at 00:30?
This gets this response:
Pretty much the whole story is in the commit. The maintainer of man is a good friend of mine, and one day six years ago I jokingly said to him that if you invoke man after midnight it should print "gimme gimme gimme", because of the Abba song called "Gimme gimme gimme a man after midnight":
Well, he did actually put it in. A few people were amused to discover it, and we mostly forgot about it until today.
The commit in question, and more commentary over at HackerNews.
Anyone know of other good easter eggs that have cropped up unexpectedly and caught users out?

The documentation you land on if you Google "man man page" might only specify -w with an argument, but that page is 7 years old.
-w or --path
Don’t actually display the man pages, but do print the loca-
tion(s) of the files that would be formatted or displayed. If no
argument is given: display (on stdout) the list of directories
that is searched by man for man pages. If manpath is a link to
man, then "manpath" is equivalent to "man --path".

The quoted snippet above is from the manual of the classic "man" package, not from "man-db" which is the subject of this article. In classic "man" the -w option is clearly documented to work without any additional arguments.
Completely pointless incompatibilities between the two implementations is probably not a desirable scenario for anyone.

Why do you assume the documentation was changed in error? Can't it have been a deliberate change to the functionality of the program?

It's actually consistent with the documentation you quoted, regardless of when it was changed, they're still consistent.
This is because the doc specifies the output to stdout, and that's exactly what you get on stdout.
The 'easter egg' doesn't print to stdout, it prints to stderr.
