Customize face editor: [Value menu] *

[Per Abrahamsen]

The "[Value menu] *" value for attributes as it currently standt
represents an unnecessary complication compared to Emacs 20.  The "*"
is cryptic, and the same information is available via the checkbox.

I suggest it is removed for 21.1, until someone find the time to make
a full implementation (i.e. remove the checkbox, and chose a more
significant string (e.g. "Unspecified" instead of "*")).

PS: I'm not on this list.
