version format must be like:
SSH-[0-9]*.[0-9]*-[^-]*( .*)?
and previous string did not conform to the requirement (too many hyphens).
based on comment from markus@openbsd (openssh maintainer)
the value of IgnoreRhosts. with `IgnoreRhosts yes' and `IgnoreRootRhosts no'
you get similar behaviour to the `-l' flag on rshd(8). this is based on
similar modification i made which appeared in ssh 1.2.27 (?)
- document that IgnoreRhosts now doesn't apply to root.
- clarify that /etc/s?hosts.equiv doesn't apply to root (it didn't before
my modification either).
- crank the version to 20001003
