purge.hash in trunk

[Skye Poier Nott]

Updated to r2945 today, is purge.hash changed or broken?

This works:

purge.url .
purge.hash .

But none of these have any effect:

purge.hash .#.#
200 0

purge.hash #.#.
200 0

purge.hash $#$#
200 0

purge.hash #$#$
200 0

(The last trunk rev I was using had #host#path but now it's  
host#path# ?  It would be nice if 'help purge.hash' mentioned the  
current expected format)
