Log:
  MFC r210428: sh: Add a regression test that tries out all arithmetic ops.
  
  The gaps in the numbering sequence cannot really be avoided, as HEAD changes
  are not necessarily merged in the same order as they are made (if they are
  merged at all).

Added:
  stable/8/tools/regression/bin/sh/expansion/arith2.0
     - copied unchanged from r201428, head/tools/regression/bin/sh/expansion/arith2.0
Modified:
Directory Properties:
  stable/8/tools/regression/bin/sh/   (props changed)

Copied: stable/8/tools/regression/bin/sh/expansion/arith2.0 (from r201428, head/tools/regression/bin/sh/expansion/arith2.0)
