[plug] mozilla - attach file from command line

[Craig Ringer]

Hi folks

Do you know if there's any way to create a new email on the command line 
in mozilla, and pre-attach a file? It's easy enough to create a message, 
just call

mozilla -remote 'xfeDoCommand (composeMessage)' || mozilla -compose

but I'm looking for an extra command or argument that can be used to say 
"Attach this file to the newly-created message".

That way, from ROX-Filer (or any other file manager with a Send-To 
function) you can say "send to: email" and have a handy pre-attached 
file. mutt can do it fine (the '-a' flag) but we're using moz as our 
standard mail client here, and it'd be ideal to find a way to do it with 
mozilla.
