Re: set-fontset-font is slow if the fontset is specified by a long name

[Richard Stallman]

    Unfortunately even the long format can't identify the
    fontset directly.  I admit that this is a mistake of the
    design.  The basic problem is that a fontset name can
    contain '*'.

Is there any good reason to use a fontset with * in its name?  If not,
we could say "that's not allowed" and make it an error to try to
create one.
