SCP URIs (draft-ietf-secsh-scp-sftp-ssh-uri-02)

[Jacob Nevins <jacobn+secsh%chiark.greenend.org.uk@localhost>]

I still think it's a mistake to attempt to standardise a URI scheme for
SCP. Apart from the fact that it's not a documented protocol, my
objection from 2003 still holds:

=-=-=-=-=-
How should filenames containing spaces be represented in scp: URLs?
Backslashes?

The scp "protocol" requires that such filenames be quoted in some
unspecified way (often using Unix shell quoting, but presumably
server-dependent).
IME, with many current clients it's up to the user to know the quoting
convention on the particular server. Either the quoting will have to
be embedded in URLs (and hence specified), or quoting becomes the
client's responsibility and the standardisation of the URL format will
not do much to achieve interoperability.
