Re: Strategy for computing "diff history" of an element?

You can use "svn log" on that one file to get all of the changed
revision numbers on that one file. You can use the SVN-API or just
parse the command line output.

If you're in a working copy:

     $ svn log someFile

If not:

     $ svn log svn://path/to/file

You can then use "svn diff -r$rev1:$rev2" to get the diff. The --diff-
cmd parameter is quite helpful since you can use your own diff command
instead of using the built in diff tool.
