Comment 102 for bug 105900

The fc-list shows similar behaviour to my test program:

mfabian@magellan:~$ fc-list Arial:style=Italic:stylelang=en
Arial:style=Cursiva,kurzíva,kursiv,Πλάγια,Italic,Kursivoitu,Italique,Dőlt,Corsivo,Cursief,Kursywa,Itálico,Курсив,İtalik,Poševno,nghiêng,Etzana
mfabian@magellan:~$ fc-list Arial:style=Italic:stylelang=ca
Arial:style=Cursiva,kurzíva,kursiv,Πλάγια,Italic,Kursivoitu,Italique,Dőlt,Corsivo,Cursief,Kursywa,Itálico,Курсив,İtalik,Poševno,nghiêng,Etzana
mfabian@magellan:~$ fc-list Arial:style=Italic:stylelang=de
mfabian@magellan:~$

i.e. requesting a certain stylelang in the pattern doesn’t
limit the result to the requested stylelang, only if the
stylelang doesn’t exist at all the result becomes empty.
