I've committed a patch which makes fc-list print unescaped fonts.

It seems to work for me without the patch... could you check again?  In
particular,

 <rejectfont>
      <pattern>
        <patelt name="family">
           <string>Hershey-Gothic-English</string></patelt>
      </pattern>
    </rejectfont>

on CVS HEAD (and indeed, 2.3.90, which is what was installed on a test
computer) causes Hershey-Gothic-English to not show up in fc-list.
