Subject: [PATCH] Cosmetic: ANSI line wipe; hide (0 packages) on idempotent
 re-runs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two nits from YuKu's laptop paste: the 100-space line wipe left a
visible gap before short summaries (now ANSI EL: \r\033[K, no
residue), and '(0 packages)' printed when nothing new was installed
(idempotent re-run / theme deps all present) — the count parenthetical
is now omitted when zero.
