New Revision: 218348
URL: http://svn.freebsd.org/changeset/base/218348

Log:
  MFC r215550: sh: Add a test that manipulates various long strings.

  It is somewhat slow, but some later changes improve it.

Added:

     - copied unchanged from r215550, head/tools/regression/bin/sh/expansion/arith6.0
