Subject: 24.3.50; doc of `defcustom': specify behavior if duplicate keyword
Date: Thu, 20 Jun 2013 13:07:42 -0700 (PDT)

Lisp code can generate Lisp code, including `defcustom's.  In this
context, it is possible for the generated code to have more than one
occurrence of the same keyword (e.g., `:type'), with different
occurrences specifying different keyword values.

The implementation, and presumably the design, of `defcustom' is such
that in case of multiple occurrences of the same keyword, the last one
wins - the others are ignored.

This should be stated in the doc, as part of the description of
`defcustom'.  Programmers should know that they can depend on this
behavior.
