True.

As some of you might know, the version I use for my regular work is
slightly ahead of 'next' (you can see where it is by running "git
log --oneline --first-parent master..pu" and find the first entry
marked as "Merge ... into jch").  After having this patch for a few
days in there and using it, I have to say that I like this change a
lot while viewing the "git log -p" output.

I still find the output from "git blame" disturbing, though.  The
first thing I do in "git blame" output is to scroll to the right in
order to identify the the area I am interested in, and this first
step is not negatively affected, because the right scrolled output 
automatically wraps long lines.

But my second step is to scroll back to the left edge to find the
commit object name and at that point, the new default output without
"S" gets somewhat annoying, because most of the output lines from
"git blame" are longer than my window width.
