A two-liner is the best I can do Joel...
rebol[]foreach n parse/all f: read %memo.txt " ^/(),."[if 1 < length?
parse/all n "-"[change/part find f n "####" length? n]]print f
It could've been a bit shorter by making duplicate 1-character words
for 'parse and 'length but we want to keep it "readable", right? (:
