Hmm, I can partially confirm: in my tests, I do see the group still
present in the *Group* buffer, but it can't be activated. The group is
present in the agent's data: the group has its own directory (complete
with space in the directory name), and it is also present in the agent's
active file (also with space).

I've only been able to get as far as figuring out that the group is
*not* present in nnml-group-alist, after nnagent has been made the
current server. Presumably that's because the reading of the active file
is still done with `read', which will only read one word, not the full
name, thus the parsing fails and this line is discarded.

It might be time to get rid of the last of the `read' tricks...
