OK, will do that then. 'readlink' is not a bash builtin, so it would need the same number of fork()s and exec() as 'symbolic-ref'. Of course, the 'readlink' binary is much smaller than git and has less to do, so it might be a tiny bit faster, but for this rare corner case it really doesn't matter. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
