Shrinking repository

From: Robert Hunter <robert.hunter_at_gen-i.co.nz>

I've just upgraded from an old Subversion (0.32) to a slightly less ancient
1.1.1, and
thought I'd try this new-fangled FSFS back-end.

I was hesitant to perform the regular dump/load cycle due to disk space --
the repository
took up a good chunk of the 1.5G partition assigned to it. But I convinced
to use another filesystem as "swap" space, and I was amazed at the results.

The on-disk size of the new repository was little more than 130M -- it had
been reduced
by a whopping 85%!

Just to be fair, I decided to create a new bdb repository and load the data
into that.
It too was smaller, but not by as much.

897M /srv/svn/original-repos
582M /var/lib/svn/new-repos-bdb
135M /var/lib/svn/new-repos-fsfs

This means that my new repository and a "svnadmin dump" take up less space
than my old repository by itself.
