While I sympathize unfortunate users who are stuck with such a broken implementation of an important basic tool, such a rewrite unnecessarily makes debugging of both test scripts _and_ real breakage harder. It actually is very useful, in the chain of &&, to see that these steps in our tests output something when they shouldn't when the tests are run under -v; you may have noticed that the tests written by me have seemingly useless "echo happy" (which always returns true) and such, and they are there for a reason. Please get the distribution fixed. - : 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
