[PATCH 6/8] t: simplify loop exit-code status variables

From
Jeff King <peff@peff.net>
Date
Mar 25, 2015, 05:30 UTC
Message-ID
<20150325053017.GF31924@peff.net>
In-Reply-To
<20150325052456.GA19394@peff.net>

Since shell loops may drop the exit code of failed commands inside the loop, some tests try to keep track of the status by setting a variable. This can end up cumbersome and hard to read; it is much simpler to just exit directly from the loop using "return 1" (since each case is either in a helper function or inside a test snippet).
