I don't know which are the legalese sophisms which the following
solution may break, but if the problem is to keep consistency
between license headers, what about to simply *include* license
headers like this:
* copyright (c) 2001 Fabrice Bellard
This would reduce the visual clutter of each file header, and
would fix the consistency problem once and for all, with all the
other advantages consequent to the code duplication avoidance.
But again, I don't know if this solution is valid *from a legal point
of view*, neither I know other projects adopting such a solution.
