Subject: make MBox::Loader#next return nil once EOF is hit
X-Git-Url: https://git.notmuchmail.org/git?a=commitdiff_plain;h=e2aa05a0ceaf03409d5979087d8c50546e53ffe1;p=sup

make MBox::Loader#next return nil once EOF is hit

Previously it was raising a debugging exception. This is a better
interface for writing unit tests against.
