This doesn't appear to correct any of the two bugs I reported
(reused ac_max, and unmatchable FGREP$), so I do not know what
this fixes exactly.

My impressions is that your change will cause the test to exit
as soon as a working tool is found, although the intent was to
try many names of the tool and return the better one.  The
original `break 2' looks correct to me: it exits the tests for 
the current name of the tool and continues with other names.
