doc/programmer/design/server.texi doesn't know about FSFS

The @node Diffy Storage section(line 647) of server.texi talks about
rediff'ing previous versions against the newest revision when wrapping
up a commit.

Would someone like to contribute new text that describes the FSFS
format, or point me at a nice section of text that can be pasted in?

Text from 1.2.0 release:

Like many other revision control systems, Subversion stores changes as
differences. It doesn't make complete copies of nodes; instead, it
stores the @emph{latest} revision as a full text, and previous revisions
as a succession of reverse diffs (the word "diff" is used loosely here
-- for files, it means vdeltas, for directories, it means a format that
expresses changes to directories).

The next section, @node Implementation, mentions only BDB as an
available filesystem. I believe a one or two line snippet that's
possibly in the 1.1 release announcement will suffice here.

/me trying to learn the internals...
