Over the years I've consistently found it to be at least an order of magnitude slower, and more error prone.

+1 for Paul, Kristian and Tomeu.

To Jon's point, I would say it will be good to have this compromise:
* Always put braces.
* If you find a place where there is no brace, you can:
a) Fix it, if and only if your commit is already changing that line.
b) If there are lots of places where style rules are violated in the
file, and the maintainer agrees, do a pre-commit fixing the style
(stating very clearly that it shouldn't be changing behaviour), and then
do your commit with the meaniningful changes.
