svn commit: r219390 - head/tools/regression/bin/sh/builtins

Log:
  sh: Test that . /dev/null returns exit status 0 and does not preserve $?.
  
  Preserving $? may cause problems particularly if set -e is in effect.
  
  It may be useful to preserve the old value of $? in the dot script but this
  must not be implemented in such a way that it would break this test.

Added:
  head/tools/regression/bin/sh/builtins/dot3.0   (contents, props changed)

Added: head/tools/regression/bin/sh/builtins/dot3.0
