about half of every patch series that gets sent to me on lkml is 
unreadable in my email client due to the default threading that 
git-send-email does. It looks like this:

and with 10 or more patches it's an absolute pain as threading depth 
increases. Furthermore, the subject lines are not aligned vertically, 
making it very hard to see the general shortlog-alike structure of the 
series, at a glance. Plus i dont even _see_ the title over a certain 
depth, as i run out of screen real estate.

So ... the question would be ... could git-send-email flip its default 
please, via the patch below? Am i missing something subtle about why 
this default was chosen?
