Dan Gohman 1880092722 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

Nick Lewycky 6a344e097c Sneaky, sneaky: move the -1 to the outside of the SMax. Reinstate the
