svn commit: r251180 - head/tools/regression/bin/sh/builtins

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.

Added:
  head/tools/regression/bin/sh/builtins/break4.4   (contents, props changed)
  head/tools/regression/bin/sh/builtins/break5.4   (contents, props changed)

Added: head/tools/regression/bin/sh/builtins/break4.4
