I didn't use git-send-email for this script because of a few 
complications with it. First, when using the --compose option, there is 
no way to pass it a file for the cover-letter. Second, it doesn't scan 
the entire patch series for recipients and will send each mail in the 
thread to different recipients - including the cover letter, which I 
find simply obnoxious. These prevent it from being used as a single 
command with a refspec for the range of patches. If you aren't going to 
do this, then using it in a loop is effectively the same as using 
sendmail. If you're using git-send-email, then you already have local 
sendmail setup.

Other than using your local git mail aliases, I don't see any advantage 
to using git-send-email. If you're using the auto-harvest feature, you 
had to dig up the proper email addresses anyway. It does however add a 
second configuration step - the [sendemail] section. I do have this 
setup myself, but enough people trip over just getting a local sendmail 
configuration working that adding git sendemail to that just doesn't 
seem worth it to me.

Is there an advantage to git sendemail that I am overlooking?

Thanks,

Darren Hart
