bug#14635: 24.3.50; Regression in Customize: no revert changes

[Drew Adams]

emacs -Q
M-x customize-face default

Make some changes.  Then choose Set for current session from the State
button.

Then try to revert your changes using button `Revert...' > `Revert this
session's customizations'.  There is no effect: no change in the
appearance of the buffer.  And trying to revert or undo edits using the
State button is also impossible: `Revert this session's customizations'
is now dimmed out.  This is with emacs -Q.

The change of state to revert to no changes seems completely broken (a
regression).
