           Summary: ssh(1) is too picky about unknown options in
                    ~/.ssh/config
           Product: Portable OpenSSH
           Version: 3.8p1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh
        AssignedTo: openssh-bugs at mindrot.org

ssh(1) fatal()s when parsing an unknown ~/.ssh/config option.

This is rather annoying since ~/.ssh/config may be shared with multiple
versions of OpenSSH as well as with OpenSSH derivatives (or even non-
derivates that just honor ~/.ssh/config), and since each such
implementation may support different sets of features and associated
config options.

At least when parsing ~/.ssh/config ssh(1) should not fatal() on
unknown options, but verbose().  When parsing options given on the
command line, however, calling fatal() seems appropriate, and possibly
when parsing $PREFIX/etc/ssh_config.
