Hello!

I have not submitted patches against an ELPA package before, so I hope
this format is OK. I tried to follow the instruction on pulling ELPA
from Git, but the make step failed for me.

The register-list mode throws an error on start-up when there are
unknown register types in the register-alist. This can happen with
window configurations and saved session state after a restart. The
reason for this is a simple line flip in the register-list-get-type
function.
