version stuff, autorevision

[Hal Murray]

Something broke in my setup and I can't figure out what's going on.

I build/test on one system, then scp to other systems so I can build and test 
there.  The scp step skips .git to reduce clutter and save network time.  
Some of the other systems don't even have git installed.

I have a kludge in the script to make wafhelpers/.autorevision-cache.  It 
does get scp-ed around.

That used to work.

Now, I'm getting:
  error: No repo or cache detected.

Building with -v says:

It did work earlier:

I think the problem is that somebody is deleting wafhelpers/.autorevision-cach
e so it is trying to use info from  .git to recreate it and .git doesn't 
exist.

Does anybody recognize what's going on and/or have suggestions to fix it?  
Anybody remember changing anything in this area recently?

I'm not sure when the last time it worked.  I haven't tried bisecting yet, 
but that's next on my list.
