Hello there,

I'm using emacs version:
GNU Emacs 25.1.1 (x86_64-w64-mingw32) of 2016-09-22

I started to thorougly read the elisp manual, and I noticed some
possible errors, therefore I attached the file with issues found until
now.  Briefly, there are some insignificant errors, the generators
apparently missing from emacs, and there is a problem with a `pcase'
example.

Than you,
Bogdan Creanga
