ksu has no man page?

So this is weird.  Dayjob is a FreeBSD and kerberos shop, and we use the  built in heimdal kerberos in base.

I had an expired root password, and ksu decided to try to force a password change on me.  (It then failed, because ipfw didn't have the privs to contact the kdc on the kpasswd port -- we only allow that from our shell servers, where people should be changing passwords).

Anyway...the man page *does* exist in /usr/src/crypto/heimdal/appl/su/su.1, but that weird behavior is not mentioned.

And apparently su has been removed from current kerberos cuts

https://github.com/heimdal/heimdal/blob/master/appl/Makefile.am lists "remove appl/su" in their changelog six years ago.

So, um....

Why is FreeBSD not shipping the existing manpage as /man1/ksu.1?  That would at least be something.

(Yes, I know from conversations with cy@ that apparently there's some coming change to using MIT, which makes this a moot point.  I'm just trying to read the tea leaves here).
