I admit that I too went looking for this option.  My solution was to create
a manifest.in, with entries similar to:

include some_dir/*.h,

and will need to duplicate my data_files entries before my sdist will be
complete.

So I agree with your sentiments, and think it makes for 2 reasonable feature
requests; data_files optionally included, and ability to define
extra_source_files, a-la manifent.in lines, in setup.py.

Would such a patch be approved?  One day I will need to fix my sdist
package, so I'd be happy to 'fix' it inside distutils itself.

Mark.
