[Fontconfig] Family name issue

[Ingo Brueckl]

It seems that all the fixed size (default X11) fonts in my misc font
directory got 'collected' under the family name 'Fixed' - at least that's
what 'fc-list : family' tells me.

However there are two fonts (the first one's created by me) which don't get
the family names expected. The font.dir entries are:

10x18.pcf.gz -ib-latin1-medium-r-normal--18-1400-96-96-c-100-iso10646-1
cursor.pcf.gz cursor

I'd expect names like 'Latin1' and 'Cursor' but get '10x18.pcf' and
'cursor.pcf' instead.

Can someone explain why there is a family collection 'Fixed' though I can't
find a rule for this and what to do to 'rename' the '10x18.pcf' and
'cursor.pcf' entries?
