The response received by http::get_state() contains a linebreak that the current split(' ') doesn’t account for, so libpijul::Merkle::from_base32 will always fail and get_state will return None despite getting a valid response.

Thanks! Since your work has already caused a number of (nice) changes in the code for pull, pulling this patch wasn’t totally trivial, and many things needed to be fixed. This is done now, thanks!
