Typo in Emacs book "An Introduction to Programming in Emacs Lisp"

[Michael Marmor]

Dear Sir or Madam,

I have found what I believe is a typo in the book "An Introduction to
Programming in Emacs Lisp".

In the subsection titled "Error Message for a Symbol Without a
Function" there is a line of text that looks like this:

(The message will go away away as soon as you move the cursor or type
another key.)

Please note the duplication of the word "away".

This is very minor, but is, I believe a mistake.

Best Regards,

Michael
