I don't think that's a bug -- running the script under 'sh -x' is not a
supported by of invoking it, but a way to invoke shell debugging of the
script.  I don't see anything unexpected in the debug output, it doesn't
print the help string three times, it is merely shown in debug output.
Redirect debug output with 2>/dev/null and you will only see what the
script prints.  Running 'build-aux/get-version-gen' works fine as
expected.
