It sounds strange to solve only the issue with NEWS, but not with
other documentation.

OK, but then the logic in your proposed change changes too radically
what we've been doing until now: it will cause Emacs to use the NEWS
in the source tree even if you run the installed binary.  That is not
TRT, IMO.

We need some way of detecting the situation whereby Emacs is being run
from a separate build directory, and using the NEWS from the source
tree only then, as fallback.
