I built mailutils at HEAD, with your fix.  I see that "folders +/"
finds all the root directories, and I don't see garbage characters in
the output.  Thanks for the quick fix.

The difference from nmh, "/bin" vs "//bin", is significant to MH-E,
so the MH-E unit tests still don't pass.

I suspect this is a bug in MH-E.  I think MH-E doesn't parse
"folders +/" correctly, and this failure is papered over by nmh's
adding an extra slash.

To my eyes, "/bin" looks better than "//bin", but maybe I don't
understand the semantics of an MH folder name.

So which "folders" output is correct, mailutils or nmh?  If mailutils
is correct, we can fix MH-E to deal with the correct answer.
