bug#3639: 23.0.95; defcustom docstring ':link' ':tag' NAME and/or LABEL?

The docstring for defcustom's keyword `:link' states:

"You can specify the text to use in the customization buffer by adding `:tag
 NAME' after the first element of the LINK-DATA; for example, (info-link :tag
 "foo" "(emacs)Top") makes a link to the Emacs manual which appears in the
 buffer as `foo'."

Shortly thereafter a description of defcustom's keyword `:tag' states:

":tag LABEL Use LABEL, a string, instead of the item's name, to label the item
        in customization menus and buffers."

If these two uses of 'tag' have identical context, then the `:tag NAME'
descriptor of the `:link' section should clarify this and/or change 'NAME' ->
'LABEL'. 

If the context of 'tag' is mutually exclusive then _that_ should
be clarified. As presented, it is not clear if `:tag' has different meanings within defcustom forms according to where it occurs.
