Feature request for `describe-char-after'

[luis fernandes]

Hello,

I would like to request that, if possible, "describe-char-after" (C-u
C-x =) also include the name of the face, the character being
described, is rendered in.

For example, if one wants to modify a particular face, one has to
find the name of the face first. So, being able to place the cursor on
the character in question and then quering everything about that
character is very convenient.
