[PATCH 1/2] cg-clean shouldn't clean untracked directories without -d

[Pavel Roskin <proski@gnu.org>]

Use the new squashdirs argument in list_untracked_files() to treat
untracked directories and their contents as a whole.  Remove a separate
pass to find untracked directories.  Adjust the testsuite accordingly.

Don't change IFS - it's no longer needed.
