Maybe of interest: this indentation style is often known as Whitesmiths style.

If you dig through some of my earlier posts here you'll find I used it as my default style because that's what I'd been using (for preference) with C++ and had what I considered (and still do) to be good reasons for using. I've switched to K&R for Perl to "fit in" with the community, but use PerlTidy frequently. Actually I've got PerlTidy tuned so well to my adopted Perl style that aside from cleaning up line wraps it almost never alters my code. It takes some work to get PerlTidy fully tuned, but it is a wonderful tool and one good reason to use Perl if you care about consistent style. I haven't found anything near as good for C++ :-(.
