Incorrect shell code regarding tilde expansion

Status in Ubuntu Manual: Fix Released
In chapter 6, page 121 we find the following snippet
If there are spaces in one of the directories, you will need to put quotation
marks around the path:
$ cd "~/Music/The Beatles/Sgt. Pepper's Lonely Hearts Club Band/"
While the text is correct in stating that putting quotation marks around the path will allow the spaces to be treated as part of the path rather than as word separators, the tilde loses its meaning when quoted. I.e. try the following in a shell:
echo '~' "~" ~
See http://www.opengroup.org/onlinepubs/7990989775/xcu/chap2.html#tag_001_006_001 about the rules regarding tilde expansion in POSIX shells.
In short, the correct command-line should be:
$ cd ~/"Music/The Beatles/Sgt. Pepper's Lonely Hearts Club Band/"
$ cd "$HOME/Music/The Beatles/Sgt. Pepper's Lonely Hearts Club Band/"
