I see ... since  . was used, it matches tailing / too. 

My "dpkg --force-bad-version --compare-versions ..." wrapper script tells me:

$ dpkg-ver 0.9.8 0.9.8.1
0.9.8 << 0.9.8.1
$ dpkg-ver 0.9.8/ 0.9.8.1/
dpkg: warning: version '0.9.8/' has bad syntax: invalid character in version number
dpkg: warning: version '0.9.8.1/' has bad syntax: invalid character in version number
0.9.8/ >> 0.9.8.1/

See the sorting order changes.  That is the problem.

Interesting. It may be a good idea to drop the tailing / from href data
when calculating sorting order.
