bad alternatives symlinks after potato upgrade

[Dan Christensen <jdc@jhu.edu>]

I just upgraded my mostly stock slink machine to potato with
"apt-get update; apt-get dist-upgrade".  Now I have both /usr/man
and /usr/share/man on my system, and neither is a symlink to the
other.  A quick glance showed no files in common between the
two directories, and they both contain around 7.5M.  "man foo"
works for foo's in either directory.  But the alternatives
system is messed up, with symlinks pointing to the wrong place.

An example is /etc/alternatives/editor.1.gz, which points to
/usr/man/man1/elvis.1.gz, which does not exist.  However,
/usr/share/man/man1/elvis.1.gz does exist.

What happened?  Would manually changing all the bad symlinks
in /etc/alternatives to point to the right place be the correct
fix?  Is there an automatic way to do this?

Thanks for any suggestions.

Dan
