--force' allows it!").

* en/book/ch07-customizing-svn.xml

perform a real diff even if MIME types indicate that it shouldn't.

Fix issue #233 ("Inconsistent example code for treeconflict").

* en/book/ch02-basic-usage.xml
(svn.tour.treeconflicts.example): Fix the "left side" label of a
couple of 'svn diff' output examples to read "revision 14" instead
of "working copy".
