Yeah upstream link is https://dev.gnupg.org/source/libgpg-error/browse/master/src/gpg-error-config-test.sh.in;50e62b36ea01ed25d12c443088b85d4f41a2b3e1, but when you got to get the raw link phabricator gives something lousy-looking that doesn't contain the commit hash. That just sounds to me like something that's going to rot.
