bug#67033: 30.0.50; Emacs Lisp Reference Manual, escapes in strings

[Richard Stallman]

In Info, in the node Strings and Characters, there is no obvious link
to the info about the read syntax of strings (or that if characters).

Neither is there any in its subnode Basic.

In the node Lisp Data Types, there is a subnode Printed
Representation.  However, that subnode does not offer any way to get
to the printed representations of specific data types, including
strings.

Its subnode Programming Types has a subnode String Type.
It does not say anythng about how to represent a carriage return
or where to find that info.

It has a subnode Syntax for Strings.  But that too says nothing
about how to represent control characters in a string constant
and gives no link for that.

A later subnode, Nonprinting Characters in Strings,
also does not say anythng about how to represent a carriage return.

I was really looking for that info -- I had forgotten it was \r -- 
and I was really looking at all these nodes, and finding no help.

Eventually I looked at nodes about characters and found the answer
there.  But the nodes about strings ought to help the user find that.
I think several of the nodes I mentioned above
should have links to the string syntax, and the main string syntax
node should have a link to the info on \-sequences for strings.
