IMHO, 'patch' is an amazingly difficult piece of code, written by
Larry Wall. Applying context diffs is not trivial -- involves all
kinds of fuzzy logic.

...whoa there. SVN sends its own binary diff format over the *wire*

pristine fulltext in .svn/tmp/. Then we use diff/patch to perform a
*context* merge into the user's existing local mods.
