Slackware does; I assume it got the idea from Debian. (for reference,
ftp://ftp.slackware.com/pub/slackware/slackware-14.1/source/ap/groff/groff.SlackBuild).
I've been planning on reporting a bug with Debian once I have time to
figure out how to.

Check "man ssh | less" to see what it looks like. If the overstrike
output is being used, you should get bold and underlines. If SGR
output is being used, you should get a load of ugly codes ("man ssh |
less -R" would show bold and underline.)
