There's test-dump-untracked-cache that will give you all the data.

data should be processed.

There's no obfuscation support in that command, unfortunately, so you
can't just send me the dump. But if you could limit it to a few
"blocks" related to the error messages, then manual obfuscation should
not take that much time (either that or just add obfuscation in
test-dump-untracked-cache.c, it's probably easier task; or I can do
this for you)

One question (I wasn't clear from your previous mail). Does "git
status" always report the same errors when run multiple times, or does
it just report once, then next "git status" is silent? I suppose it's
the former case..
