I think it doesn't make sense to display the hashes directly. That would work for 
one hash maybe, but not for several, long hashes. All in all, there is a lot of 
additional information about files that MirrorBrain now stores. 

The current solution is to display a "Details" link, nothing else. And that links 
to the page which shows the complete known metadata.

As such, this issue can be closed as resolved.

From the old TODO file: 'add "md5" and "sha1" or "checksums" link to 
mod_autoindex_mb. Make it configurable so it can be switched off for the very 
large directories that are already slow to show anyway.'

(blocked by issue 40)

The directory indexes that Apache generates could include links to hashes, like 
md5 and sha1. In fact, they could even display the hashes directly, if that would 
make sense.
