yes, understood.

I tried a the project prefix, and that works for the format-patch 
command. But it not work for patman.

here is my steps:
   git config format.subjectprefix "U-Boot"

Now, when I run git format-patch, the generated patch will have 
"[U-Boot]" prefix. But if I run "patman -c1 -n", the [U-Boot] prefix is 
gone.
It seems patman overide the format.subjectprefix  option of git. Do you 
have an idea about what is the difference between the run "git 
format-patch -1" and "patman -c1"?
thanks.
