sshd -t to test configuration file syntax?

[Pekka Savola]

Hello all,

sshd configuration file options change from one release to another.

If you forget updating sshd_config, sshd will not start.

This is especially painful for update scripts etc. where you can't do e.g.
'sshd -p 2022' to see if it's okay.

May I suggest some option, e.g. sshd -t, which would test config files and
other obvious issues and return an errorcode if something is broken?

Does this seem useful?
