New Revision: 206491
URL: http://svn.freebsd.org/changeset/base/206491

Log:
  sh: Test that bogus values of PWD are not imported from the environment.
  
  Current versions pass this test trivially by never importing PWD, but I plan
  to change sh to import PWD if it is an absolute pathname for the current
  directory, possibly containing symlinks.

Added:
  head/tools/regression/bin/sh/parameters/pwd1.0   (contents, props changed)

Added: head/tools/regression/bin/sh/parameters/pwd1.0
