builtin/diff: update usage comment
A comment in cmd_diff() states that if one tree-ish and no blobs are provided, (the "N=1, M=0" case), it will provide a diff between the tree and the cache. This is incorrect because a diff happens between the tree-ish and the working tree. Remove the `--cached` in the comment so that the correct behavior is shown. Add a new section describing the "N=1, M=0, --cached" behavior. Next, describe the "N=0, M=0, --cached" case, similar to the above since it is undocumented. Finally, fix some spacing issues. Add spaces between each section for consistency and readability. Also, change tabs within the comment into spaces.
