BTW, the default prompt for `customize-face' has several problems.
1. The `face' property on a character under the point takes precedence
over the face name extracted from the buffer. So if the point is
located on the face name in the `defface' specification, then the
default will be `font-lock-variable-name-face' instead of the face
from `defface', because the face name is fontified in that font-lock
face.
The patch below joins all faces (from `face' property and face names
under the point) into one list. The patch is backward-compatible
for the argument `multiple' since it places faces from the `face'
property in front of the face name extracted from the buffer, so
the first element will be the same as now if `multiple' is nil.
2. When the `face' property has a list of faces, these faces are
displayed in the default prompt as words separated by comma.
It would be natural to expect that M-n in the minibuffer will allow
their editing, but this doesn't work.
The patch adds the default argument for completing-read, and splits
the result afterwards. One drawback of such approach is that it
doesn't allow completion for multiple face names (there is the file
emacs-lisp/crm.el distribued with Emacs that could be used here but
it is not up-to-date). Also it can accept invalid face name (to
allow a comma-separated input string to be accepted), but this is
not a big problem. `complete-in-turn' still works on a single face.
