bug#13565: 24.3.50; (emacs) `File Registers' typo: ?R should be R

["Drew Adams" <drew.adams@oracle.com>]

In all of the register sections of the Emacs manual, this
convention is used:
 
 "Each register has a name that consists of a single character,
  which we will denote by R"  - (emacs) `Registers'
 
In `File Registers' there is this text:
 
 Here's the Lisp code used to put a file name in a register:
 
     (set-register ?R '(file . NAME))
 
 For example,
 
     (set-register ?z '(file . "/gd/gnu/emacs/19.0/src/ChangeLog"))
 
The part before the example is a mismash, a mix of
specification/template and literal example.  For it to serve as a
specification (template), `?R' needs to be corrected to `R'.
For extra clarity, the accompanying text can say, e.g.:
 
 "Here's the Lisp code used to put file NAME into register R:"
 
(FILE would be better than NAME, here, BTW.)
 
These changes will bring this node in line with the others of section
`Registers'.
