Bug#484451: mention ssh-vulnkey on more man pages

[jidanni@jidanni.org]

Package: openssh-client
Version: 1:4.7p1-12
Severity: wishlist

Perhaps ssh-vulnkey should be mentioned on one or two more of these,
e.g., ssh(1). At least in SEE ALSO.

$ zgrep -c vulnkey /usr/share/man/man*/ssh*|perl -lnwe 's@.*man/@@;@F=split /:/;print "@F[1,0]"'|sort -r
