Subject: [PATCH] git-version-gen: fix preceding change

* build-aux/git-version-gen: Use the contents of the -git file
when its first line has the proper form (fixing a reversed test).
Also, reference the file only once, rather than three times.
Also, double quote $tarball_version_file in preexisting code.
