Fix another regression with aliases

The last commit (1415c8f9b89699000ef8d864ff8f0e1bebca4a5f) fixed the
issue with pipes, however, it did not fix it for IO. This patch adds
some logic for the aliased verse to inherit the properties of the
original verse, so that recite works properly for all verse types
(regardless of IO, couplet, or meter).
