From where I'm standing, it's an argument to just use spaces for both C 
and C++.

But anyway, I don't think project migration is a good problem example. 
There are a lot things to do during that kind of migration, and adding 
an `indent-tabs-mode' to dir-locals.el should be trivial in comparison. 
A project that lives long enough to migrate must already have this file.
