Larry will probably also comment on this, but in patch 19 it is stated that
from now on `$' will only match at string end (or at the newline just before
the end) when $*==0. So s/\n+$// works. Actually the only confusion that
remains is whether the LAST newline will be substituted. Maybe Larry can
give the rules.

Unfortunately, the manual ``page'' has not been updated with the patch.
