generic file extension

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
<presets>
    <Copy>
      <label>Copy media streams</label>
      <params>-acodec copy -vcodec copy</params>
      <extension>*</extension>
      <category>Copy</category>
    </Copy>
  </presets>
2.
3.

What is the expected output? What do you see instead?
Since it attempts to be a generic 'copy stream' preset,
 notwithstanding codec or container, it would need to use the extension
 of the input file for the output file. However when I tried to use '*'
 (asterisk) in the 'extension' tag, ffmpeg was given the '*' char
 literally:
 /usr/bin/avconv -y -i "/tmp/aq.mp4" -c:v copy -c:a copy "/tmp/aq.*"

 and understandably got confused:
 Unable to find a suitable output format for '/tmp/aq.*'

What version of the product are you using? On what operating system?
libavcodec-extra-53 v0.8.5 from Medibuntu
- Xubuntu Precise
 - WinFF 1.4.3 from the PPA

Please provide any additional information below.
Is it possible to specify a generic file extension in WinFF?

Maybe when implementing, use something like

/wildcard/

Instead of * to avoid confusion.
