[sshd.c servconf.h servconf.c sshd_config.5 auth.c]
Add support for conditional directives to sshd_config via a "Match"
keyword, which works similarly to the "Host" directive in ssh_config.
Lines after a Match line override the default set in the main section
if the condition on the Match line is true, eg
AllowTcpForwarding yes
Match User anoncvs
AllowTcpForwarding no
will allow port forwarding by all users except "anoncvs".
Currently only a very small subset of directives are supported.
