They became unnecessary for me because the part of fontset
debugging that used those functions were finished.  It's my
fault to keep those functions in a half-finished status,
sorry.  Their precise behaviour is not clear, and thus not
well documented.

As I still don't have a clear image about what kind of
information font-info should return, and how describe-font
should show that information to user, I don't want to change
font-info itself at the moment.  So, I'd like to do these:

(1) Explicitly say "Internal use only."  in the docstring of
    font-info.

(2) Improve describe-font to show more reasonable messages
    (as already suggested).  Improve the docsting.

As I wrote, I don't know.  It seems that something (perhaps
the function `query_font_func') is not correctly working on
Windows port.
