The change of 2001-11-01 introduced a bug whereby some recursive
listings didn't have a blank line between per-directory groups of files.

(print_dir): Print a newline before each directory name
except the first one, rather than after each except the last, since
now (after the changes of 2001-11-01) detecting whether a `pending*'
is the last would involve more work.  Reported by Andreas Schwab.

This change has no net effect.
(main): Remove always-true conjunct and add a comment.
