Mime info - is 'command=open %f' supported any more

[Damon Chaplin <damon ximian com>]

I'm looking at:
  http://bugzilla.gnome.org/show_bug.cgi?id=75620

The bug-buddy.keys file is:

application/x-core-file:
        icon-filename=/gnome/head/INSTALL/share/pixmaps/mc/i-core.png
        open=bug-buddy --core=%f


Firstly, is 'open' supported any more in the .keys file?
Or will it only look in bug-buddy.applications (if that is installed)?


Secondly, do we support anything like the '%f' substitution now?


Finally, who knows what the mime info formats are now?
The docs are way out of date so it is difficult to know what is supposed
to work and what is using bad .keys files.
