New Revision: 214244
URL: http://svn.freebsd.org/changeset/base/214244

Log:
  MFC r213926: sh(1): Clarify subshells/processes for pipelines.
  
  For multi-command pipelines,
  1. all commands are direct children of the shell (unlike the original
     Bourne shell)
  2. all commands are executed in a subshell (unlike the real Korn shell)
