Author key IDs may contain white space (eg, 'My Name my.email@gmail.com'), and, so, $AUTHOR needs to be quoted when used.
While I was touching the code, I also added $AUTHOR to @EXPORT_OK. And I added some documentation about the $AUTHOR variable and $ENV{MODULE_SIGNATURE_AUTHOR} default initializer.
