Same for me. However: the (L)GPL allows even an unmodified
redistribution under a later license. It is up to upstream to decide
whether he chooses the original or a later one. And since I take these
files from upstream, not from the original author, I am bound to his
decision, independently whether the files are modified or not.

Therefore, if he chooses to redistribute the files in src/wcs/ under
GPL-3+, than this is the license for these file, and it should be
documented as such under debian/copyright. And in this case, the
redistribution under a GPL-3+ is clear (by adding the according
statement to the file headers).

The reason here is not modification (although it makes this case clear),
but redistribution. Upstream has chosen to redistribute the files under
GPL-3+, and if we want to use these files, we have to respect this.
