I'm seeing the same here, also when doing:

  rm .git/index
  git reset
  git status

after this, `git diff' also shows what changed in those files (basically
every line). It's all whitespace characters, as `git diff -w' is empty.

Turns out EOLs changed, I suspect this is due to the eol overrides in
contrib/bc/.gitattributes. If I comment those out, "git diff" is silent
again.

Cheers,
Michael
