create foo with CRLF endings, then ...
$ git config core.autocrlf input
$ git add foo
$ git commit -m x foo
Created commit a9e9d4e1b88087462a4e15ff9044fa31e16d11bc
  1 files changed, 935 insertions(+), 0 deletions(-)
  create mode 100644 foo
$ git diff

diff --git a/foo b/foo
$ git status
# On branch master
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#       modified:   foo
#
$ git add foo
$ git status
# On branch master
nothing to commit (working directory clean)

--- git should not show a just checked in file as being different.
Note: a simple "git add foo" clears the above up, as would
git-update-index foo

Also, if I invoke git-gui on the above repository showing foo as modified...

1) foo shows up in the "Changed But Not Updated" list.
2) Clicking on foo gives message box with "No differences detected. ...
    Clicking the "ok" button invokes a rescan, back to step 1.
3) Adding foo to the commit list in git-gui works.
4) Committing the above from git-gui gives a commit with no
    changes (commit is made, shows up in git log, but has no
    changes associated).

--- I don't think git-gui should make create an empty commit in the 
above case.
