Dealing with FTP servers that allow direct retrieval of full path
names but not the 'cwd' method was an issue. In the end, we came up
with a description in the standard that didn't match current practice,
but was at least unambiguous (you could really tell what a ftp URL
meant) and portable (you wouldn't have to know what operating system,
brand of unix, etc. the remote FTP server was running).

I imagine currently released clients and servers haven't tracked the
proposed standard; I hope they do.

In the meanwhile, the short answer is that you can't reliably give out
ftp URLs for sites/files where cwd A; cwd B; retr C isn't equivalent
to retr A/B/C.
