Show changes being commited as a patch appended to the commit message
buffer. If the original patch is different from the patch extracted from
the commit message file the original patch will be reverted and the edited
patch applied before completing the commit.
Due to limitations with cg-patch this can only be used when commiting
from the project root directory. The error handling if the either the
original patch or the edited patch does not apply is not optimal, since
cg-patch will not report errors properly.

I do not do Porcelains, I am not a Cogito user, and I generally
do not like encouraging people who are playing an individual
developer role to commit something that has never existed in
their working tree (hence by definition never been tested),
but...

I suspect at least you should be able to use checkout-index for
the first one instead of cg-patch.

I am curious since you have also used this phrase in the past: didn't
you do your own jit porcelain once and are you saying that git does not
ship with it's own porcelain?

I see your point. I mostly intend to use it for fixing small typos in
comments and documentation. It can help to cure some "post-commit
stress". Also I hope you will agree that it is always a good idea to
review your changes one more time although I agree it might be a little
silly.

Oh, great, thanks. I guess I should work some more on the git docs to
get to know these kind of things.
