Add $ scp --version So we can tell the version.
You can run "ssh -V" to get this information. We don't intend to add another flag for it, sorry.
Please mention that on the scp man page. I think all man pages mention how to get the current version. Though the user might think asking program A for the version of program B might have risks, it should still be documented.
closing resolved bugs as of 8.6p1 release
