23.0.60; font fails

["Robert J. Chassell" <bob@rattlesnake.com>]

In GNU Emacs 23.0.60, a visible-to-users font fails.

In the `Misc' sub menu, mouse-set-font (<S-down-mouse-1>) works for
two fonts, 9x15 and 11x18, that surround 10x20 but fails for 10x20
itself.

GNU Emacs reports

    mouse-set-font: Font not found

Currently, this is to say, in this morning's CVS snapshot (as well as
in the past), x-fixed-font-alist has

     ("9x15" "-misc-fixed-medium-r-normal--15-*-*-*-c-90-iso8859-1" "9x15")
     ("10x20" "-misc-fixed-medium-r-normal--20-*-*-*-c-100-iso8859-1" "10x20")
     ("11x18" "-misc-fixed-medium-r-normal--18-*-*-*-c-110-iso8859-1" "11x18")

although the -Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO8859-1
which I see on an instance of Emacs 23.0.50 from before the merge is
now -Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1 with
ISO10646 rather than ISO8859 and
-Misc-Fixed-Medium-R-Normal--18-170-75-75-C-90-ISO8859-1 which I see on
an instance of Emacs 23.0.50 from before the merge is now
-Misc-Fixed-Medium-R-Normal--13-120-75-75-C-80-ISO10646-1 with both
ISO10646 rather than ISO8859 and a height of 13, not 18.

i.e. -Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO8859-1 -->
     -Misc-Fixed-Medium-R-Normal--15-140-75-75-C-90-ISO10646-1

and

     -Misc-Fixed-Medium-R-Normal--18-170-75-75-C-90-ISO8859-1 -->
     -Misc-Fixed-Medium-R-Normal--13-120-75-75-C-80-ISO10646-1

even though the ISO8859 fonts are in  x-fixed-font-alist
