bug#3820: 23.0.96; Emacs Lisp typo

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the [email protected] mailing
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In 34.3.1.1 Emacs Lisp Reference ,
     Note that `\' also has special meaning in the read syntax of Lisp
     strings (*note String Type::), and must be quoted with `\'.  For
     example, the regular expression that matches the `\' character is
     `\\'.  To write a Lisp string that contains the characters `\\',
     Lisp syntax requires you to quote each `\' with another `\'.
     Therefore, the read syntax for a regular expression matching `\'
     is `"\\\\"'.
The last sentence , it should be " .... matching `\\' is `"\\\\"'  ".

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.96/etc/DEBUG for instructions.
