I think the documentation might be bogus. The released 1.8 server
parses get-dir using the format:


where "?B" is optional. Implementing the documented format would be:


but I think that would break old clients that send "l" but do not send
"(?B)", i.e. our clients, as well as breaking third party clients that
try to use the released format.

I suppose we could attempt to "correct" both the documentation and the
implementation to use the format:


which would work with our old clients, but that would still break any
third party clients trying to use the released 1.8 format.
