I hate to be the one to say this, but I don't think it is 
reasonable in the packaged release. In the dev version, 
absolutely, but the packaged release is not a git repository, but 
still includes the makefile...

However, let's not let the release compromise the development. 
The release generation script can run git ls-files itself and do 
some string replacement in the relevant files.
