That's not correct, Greg. The filename revlog.py is seeing is the
unencoded filename. If it has a problem with a file, it will throw back
the unencoded filename.

I hacked the contents of the real file .hg/store/data/_test.txt.i inside
a testrepo and got:

  $ hg --traceback up
  Traceback (most recent call last):

  RevlogError: index data/Test.txt.i is corrupted
  abort: index data/Test.txt.i is corrupted!

The filename encoding is done by the store opener, which is a layer
below revlog.py.

No, there wouldn't be, even if Richard had no problem. That's an
artificial internal name. There is not such path in the filesystem. At
least not for a repo using a recent enough repo format (e.g. fncache,
dotencode).

Extensions used might be interesting too.
