This looks OK, nmbug works as it used to be. I did not test cloning but
the oneline change in the patch looks good (just adds that config branch).

The nmbug-status change also looks good... and it works (tried using --config
option as I did not have working tree of config branch checked out just now).

But why is the NEWS brurb added deep into 0.19 NEWS content ?
