Add -K option to pkg_add and pkg_info.
  This option saves packages to PKGDIR (if defined or current directory by default)
  as they are downloaded.
  Silent a warning when -n is used and package has a +DISPLAY file.

  When using @cwd %%FOO%%, we must ensure to return in the original
  prefix later, but doing so with @cwd %%OLDPREFIX%% (having
  PLIST_SUB+="OLDPREFIX=${PREFIX}") hardcodes the value in the packing
  list. That's not really a problem when dealing with ports but that's
  a problem with packages since pkg_add -p option only overrides the
  first @cwd occurrence.

  This patch allow us to use @cwd without any argument. If no
  directory argument is given, it will set current working directory
  to the first prefix given by the @cwd command.

    Remove '\n' since it's redundant in case if file doesn't exist while
    running 'pkg_info -g'

This makes it possible to "portupgrade `pkg_version -q -l '<'`".
