In the same obarray?

In the same obarray?

Anyway, a good reason (finally).  And not so obvious.

Faces are symbols, and I agree that it is generally not good to accept a symbol
name in place of a symbol as arg.  I retract the request, based on your

In practice, 99% of the faces passed as args will be interned in `obarray' (not
in some other obarray), so there is still some argument for the convenience of
accepting a string name.

But to avoid confusion and explicitly documenting which obarray would be used if
a string is passed, I agree with you after all.
