bug#17996: 24.4.50; `theme-value' in (elisp) `Standard Properties', `Variable Definitions'

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

Node Standard Properties says this:

 `customized-value'
 `saved-value'
 `standard-value'
 `theme-value'
      These properties are used to record a customizable variable's
      standard value, saved value, customized-but-unsaved value, and
      themed values.  Do not set them directly; they are managed by
      `defcustom' and related functions.  *Note Variable Definitions::.

But node Variable Definitions says nothing about `theme-value'.  There
is no explanation of it in the manual.  Seems like an oversight by
whoever added `theme-value' to this list.

Please document `theme-value', at least to the degree that the others
are documented.  Perhaps the proper place to document it would be node
`Custom Themes'.  (And then correct the cross reference for it in node
Standard Properties.)
