State-Changed-Why:
From code reading, your fix is not quite right. It uses ,\n as a hint to
a continuation line, but this approach allows for false positives as well
as false negatives.

Instead, we have to check (in a new state) for whitespace at the start of
a line, and delay add_recipient() until we have checked that a new line
is no continuation line. add_recpient will have to make sure not to use
the \n verbatim afterwards.

Fix pending implementation and test.
