"git-version-gen" prints "Print a version string." three times

"sh -x build-aux/get-version-gen" outputs: + scriptversion=2022-07-09.08 + me=build-aux/git-version-gen + expr 2022-07-09.08 : \([^-]*\) + year=2022 + version=git-version-gen 2022-07-09.08 Copyright (C) 2022 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later
