Author: jilles
Date: Sun Mar  7 15:08:42 2010
New Revision: 204836
URL: http://svn.freebsd.org/changeset/base/204836

Log:
  sh: Add various testcases for here documents.
  
  They are mainly about expansions in here documents but because all the
  testcases are in $() command substitution, we also test that $() command
  substitution is recursively parsed (or very close to it).

Added:
  head/tools/regression/bin/sh/parser/heredoc1.0   (contents, props changed)

Added: head/tools/regression/bin/sh/parser/heredoc1.0
