No, a patch file is not the same with diff output. Patches in the mailing
list mostly include some meta information like commit message, commit date,
author name etc. in addition to diff.
That's why git diff will probably find differences between a patch
downloaded from the mailing list and your patch created by git diff.
If differences are only in meta info, stats, indexes etc.and not code
itself, then it should be good.

You may use "git format-patch" to create a patch with similar format to the
ones from the mailing list. But it wouldn't be exactly the same since
dates, commit messages etc will be different.

Alternatively, you can use "git am <patch_name>" to add the patch as a new
commit to your current branch. Then you'll have master + patch.

This is just bad. Needs to be updated properly.
