Currently, if the locale is UTF-8, no CJK fonts are installed, and someone
does XCreateFontSet() with a font name of "*", we end up asking the server
to list the (non-existent) fonts 11 times for each CJK encoding, which can
take a while.

A * wildcard can match multiple components in a XLFD name in XListFonts(),
so there's no need to try adding more than one to get a match.

We do try once with a leading '*-' in case the fontname isn't a full
well-formed XLFD name, maybe even that isn't needed?
