Empty dot at the beginning of a line is also empty dot at the end of
the previous line.

I'm not justifying the behavior, just explaining it. This is really
old code with, I admit, some quirky properties. I often think of
rewriting the address code in sam and acme but never do, because a
rewrite would change the behavior of corner cases and break people's
scripts.

Let's move on.
