This is to keep git-stash from getting confused if you're debugging
unpack-trees.

This code path is only affected when DBRT_DEBUG is defined ("Daniel 
Barkalow's Roasted Tomatoes"?).  So technically, I do not really see why 
this is part of this patch series...

"Daniel Barkalow's read_tree" (which is what that code was called when it 
was added). I needed to enable this debugging in order to debug this 
series, and found that enabling debugging caused tests to fail, so I fixed 
that in the series. To the extent that this matters at all, having it in 
the series that could need debugging makes sense.
