Weird style for an RFC I'd say... but anyway, that's some names at least.

BTW, that spec is now at version 13:

http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13

Since the names aren't really set in the standard then anyway, we can just go
with a set we think are fine. Or possibly we just use the defined numbers
instead to skip the translation to numbers in libcurl.

If we want to re-use an existing option I figure CURLOPT_QUOTE would fit, but
then we really need to pass in strings for the commands.

We must use their functions to perform the commands, or we come up with a more
conveniant way we think libssh2 should offer this functionality with, and I
can push for that way in the libssh2 project (me being a committer and all
there).
