Documentation: do not blindly run 'cat' .git/HEAD, or echo into it.

Example: let's say I had renamed `commit.c` to `git-commit.c`, and I had
done an "git-update-index" to make that effective in the index file.
"git-diff-files" wouldn't show anything at all, since the index file
matches my working directory. But doing a "git-diff-index" does:
