[Fontconfig] fc-match and fc-match --sort disagree

[Satya Narayan Mishra]

Hi 

I am new to fontconfig and don't know how all the innards work. I tried 
to look in the docs, but didn't come up with anything.

When I run fc-match Symbol I get Vera.ttf: "Bitstream Vera Sans" "Roman"
When I run fc-match --sort Symbol | head -1 I get: 
opens___.ttf: "OpenSymbol" "Regular"

I, of course, want the second to be used in the applications.

I have in /etc/fonts/local.conf .
<alias>
  <family>Symbol</family>
  <prefer>
      <family>OpenSymbol</family>
      <family>Standard Symbols L</family>
  </prefer>
</alias>


I would appreciate any help.

Satya
