Yes, to minimize number of patches moving files (and breaking history for
some tools).

The changes are only in Makefile and include lines, right?
I think it's not a big deal to have small changes. But maybe it will make
difficult to read the move with some tools.
Feel free to adopt the solution you prefer if nobody else has an experienced
opinion.
