Thanks.
I checked with git send-email , there is no line wrapping. maybe gmail just has
the feature which text be split into lines of about 78 characters in
gmail web clients.

if add '>' before the line which exceeds 78 characters in gmail web
clients, this line will not be wrapped.

I will sumit v4 version for you.
