Author: jilles Date: Fri May 31 14:45:25 2013 New Revision: 251180 URL: http://svnweb.freebsd.org/changeset/base/251180 Log: sh: Add test cases for break outside a loop. In most shells (including our sh), break outside a loop does nothing with status 0, or at least does not abort. Therefore, scripts sometimes (buggily) depend on this.
