I never understood why you doubted that the default was 72
way before I added the C pretty printer.  I can understand you
don't like it; but that should not involve doubting the facts.

Again this argument is making a sort of revisionism.
The 72 default was added to g++, and other front-ends (in reality
at the time, only C could be affected) decided not to.  Over the years, we
have moved to share more and more codes with other front-ends.
The fact that other front-ends have been using more and more of the
code that was designed for g++ should not be argument to change the
default for g++.  It should be other reasons.
