With encryption on filesystem level files in repo are not saved as
binary (in terms of svn). Svn with repo works like it works before.
Drawback is that OS has to compress and decompress file every time you
need to commit/checkout.
Diff would be useless if you encrypt every file before commit, and send
it as binary, and that is not this situation.
