You also modified the patch, and you carried it, so you should also have
added your own SoB line. ;-)

I would also note that I only cjhanged those three packages, just as an
example and tentative for the _SAME_SOURCE_AS feature. There might be
other packages that share the same sources, and we'd need to convert
them of the _SAME_SOURCE_AS feature is accepted.

Regards,
Yann E. MORIN.
