I think this change broke `C-h S' in Custom buffers:
emacs -Q
M-x customize-option RET fill-column
Put point in Fill Column
C-h S
You get prompted with: Describe symbol (default Hide-fill-column), which
is of course undocumented.
Before, the prompt was:
Describe symbol (default Fill-Column), and typing RET would open an Info
buffer without problems.

I'm not saying the change is bad.  I was just trying to see if this
change will fulfill the request in Bug#400, and I guess it does: C-h v
seems to work just fine, but I guess info-lookup-guess-custom-symbol
wasn't ready for the change.
