line wrap and rebase question

[Elizabeth Ferdman <gnudevliz@gmail.com>]

Hey Alison,

Good morning! I received some not so good feedback from Greg that I want
to fix and I have a bunch of questions. The plus side is that maybe
some of the answers could go into the tutorial.

First he said "please wrap your changelog comments at 72 columns."

Is this something I add to my .vimrc? I've been using "git commit -m".
is that causing the issue? I thought git commit messages were supposed
to be less than 50 chars anyway. I'm confused. 

The other issue was that my commit didn't apply to his tree. He says
please rebase and resend. I think I need to do:

$ git fetch origin
$ git rebase origin/staging-testing
Then reformat the patch?
$ git format-patch -o ~/mypatches/ HEAD^
$ mutt -H <file>

So I don't need to uncommit/recommit?

Thanks,
Liz
