Minor improvements in manuals

* doc/lispref/variables.texi (Local Variables): Make more clear
that local bindings of 'let' are in effect only within the body.
Suggested by Marcin Borkowski <mbork@mbork.pl>, see
https://lists.gnu.org/archive/html/emacs-devel/2018-03/msg00217.html
for the details.

* doc/emacs/programs.texi (Matching): Fix a typo.  Reported by
Alex Branham <alex.branham@gmail.com> in emacs-manual-bugs@gnu.org.
Improve indexing.
