I'm not convinced that we need to worry so much about all these details.  What 
if we just check (based on timestamps of files in /etc/setup/*.lst.gz) whether 
anything has been installed into /usr/info or /usr/share/info since we last did 
this check.  If so, then just do exactly what the current update-info-dir.sh does.

autorebase can't get away with anything so simple, but it seems to me that this 
is good enough for update_info_dir.
