Re: git-diff not showing changes (corrupt repo?)

Perhaps you are confused by the fact that "git-diff" with no options
shows the difference between the index and the working tree? Did you try
"git-diff --cached"?

after I commit the new changes--at that point, "git-diff-tree HEAD^ HEAD -p" 
spits out a nice patch, but "git-diff HEAD^ HEAD" gives nothing.

That doesn't seem right. Can you reproduce this, or at least show us the
command you used?

$ git status
# On branch bak_linear-checks3
nothing to commit (working directory clean)
$ echo "test" >> Makefile
$ git status
# On branch bak_linear-checks3
# Changed but not updated:
#   (use "git add <file>..." to update what will be committed)
#
#       modified:   Makefile
#
no changes added to commit (use "git add" and/or "git commit -a")
$ git diff
$

OK, that does seem wrong. If you run git-diff-files, does it produce the
expected output?
