RE: read-face-name bugs

[Drew Adams]

        1. read-face-name's prompt arg should be like every other prompt
           arg. It should not automatically add a colon and space. Besides,
           the doc string mentions that you shouldn't add a space (without
           saying why), but it neglects to mention that you shouldn't add a
           colon either.

    It is an internal facility, so its interface isn't crucial.

I didn't say it was crucial; I said it was inconsistent and inconvenient.
Why create an exceptional interface and then have to add stuff in the doc
string to compensate for the confusion that exception introduces? What is
gained by this?
