For the purposes of only generating doc patches, you only need to know 
and apply a handful of git commands.
Most of the supposed difficulties of working with git revolves around 
nonlinear histories. I see very little potential for that with pure docs 

You aren't tied to linux either.  ffmpeg is perfectly compile-able and 
testable on Windows. I do it regularly, but even that's not needed here.

It's nice to know help is available, and that's appreciated. But let me 
first look around at my old notes and see what all needs to be done.
What can be done in the meantime is for someone to start a wiki or blog 
or forum and solicit, collect & curate requests for documentation changes.
What do users most want answered or documented first?
