[Bf-committers] Blender command line args

[Campbell Barton]

Hi Chris,
Blender internally uses # to represent the frame number, I didnt add or 
change this, was just documenting thats how it alredy works.

Blender seems to use %04d, which could be annoying if you use all 300000 
frames in an animation.

As for the order of args- I wasnt saying its a bad thing. its actually 
useful when you want to work on multiple blend files or run multiple 
python scripts.
But its not documented, and is the kind of thing that relay confuses 
people who are not inclined to read the source code.
