Good. > git am 0001-change-file-format.patch Running this right after 'git format-patch' will try to apply the patch, but your latest commit already includes those changes. So there is nothing to apply, and 'git am' fails. Normally you would not use 'format-patch' and then try to apply the patch again, but rather send it to someone else, who could then apply your changes. You could use 'git am -3 0001-change-file-format.patch', which falls back to a three-way merge, which should tell you something like: No changes -- Patch already applied. If you want to check that the patch applies correctly, you can use 'git reset --hard HEAD~1' (make sure you don't have any untracked changes you don't want to loose first), and then use the 'git am' command from above.
