true(1) sometimes lives in /usr/bin/, and so this test fails on such systems. We also can't use which(1), because it's apparently not POSIX and Debian complains about it [1]. We also cannot really create a script and chmod +x it, because this is a symlink case, execbit case is slightly below. So let's use something that we know is executable, but not hg itself.
