Several things we'd need to consider if we go this way:

 . AFAIK, the script you mention currently supports only C sources;
   we'd need to see how well it supports C++
 . Some files in our tree are neither C++ nor C: there are Python
   files, Guile files, shell scripts, and Texinfo files, to mention
   just a few: what to do about them?
 . Last, but not least: we'd need detailed instructions for how to
   produce the commit log messages under this regime, because the old
   conventions will not be valid anymore.
